Mike, what do you use for roof sealant? I bought a 16x7 enclosed trailer new in 2016 that has metal sheet roof with 2-3" wide corner trim on it. I noticed this year after sitting all winter some water stains on the inside wood panels that looks to be coming from over the side door area. I haven't dug into it to see if I can find where it's actually leaking from yet. But on the roof on all the seams it looks like they used a paint brush to slop on some thicker sealant. Figuring I will need to reseal these seams.

Do you recommend resealing trailer roofs every so many years? We have a travel trailer also that has the rubber roof on it and when I was up there last year replacing the AC fan it looked like the sealant was pretty dried out. Should probably redo that this summer also. Do I need to get all the old off, which seems like a chore if even possible. Or do they make something I can just go over the factory stuff on? Thanks

Scott, I am **** about roofs as a leaking roof can and will destroy a perfectly good RV in very short order.

I generally walk my roof at least twice a year, more if something dictates another look. The fall or last walk of the season is usually accompanied by a thorough wash & wax using a good quality car wash/wax detergent and a soft bristled brush to thoroughly clean the roof before putting it away for the winter. I then walk it when I bring it out of storage to ensure nothing changed and nothing cracked over the winter. During the walk I look at each of the roof penetrations to ensure the lap sealant is still bonded to the roof and whatever component it is sealing, such as a roof vent or skylight. It is usually quite easy to tell when the sealant becomes disbonded with the surrounding material as it will begin lifting on the edges. I also look for cracking right down the middle or the actual joint itself, if it is put on too sparingly it can spread so thin that the joint begins to show through and a crack will appear in only a couple of years.

As for what sealant I use, it depends on the roof material itself, but generally I am a big fan of Dicor Self-Leveling Lap Sealant. Don't be bashful with it and apply it liberally and it will self-level and look very nice and tidy when it dries. It stays flexible and really does a great job of sealing and staying pliable. IF a roof is properly sealed it shouldn't have to be resealed every year. Monaco did a great job on the original sealant back in 2002 (2003 Model year) when our coach was built and I only on a couple of occasions had to remove some lap sealant, clean with mineral spirits and reapply. Very seldom actually. In fact, my skylight project that I showed here from back in 2023 the sealant was original. The Dicor that I applied when I did the Winegard Trav'ler back in 2009 has been untouched since I installed it.

The better the build quality of the RV, the less you should have to reseal penetrations as there is less flex and movement to break the seal.

I would use this, from 3M…

Dynatron™ Auto Seam Sealer Caulk​




No offense, but I don't know that I would agree. On things like roofs or other structures that are paramount to an RV's life, I don't know that I would wander off the beaten path as far as what works, what doesn't and what is engineered to work. Not saying that would not work or would fail, but I have had decades of success using Dicor and would suggest sticking with a known commodity and something with a high success rate for its intended purpose.

3M makes excellent products, especially for automotive and industrial solutions, but personally I'd stick with what I know works without having to wonder after the fact. But that's just me.

I have used 3M 5200 to bond/seal a vent to a camper roof and it worked for as long as we owned that camper. I know the couple who bought it and there's been no mention of problems with it. (Those who claim that 5200 is a permanent, forever install have never heard of a heat gun, I'll guess.)

That said, I used Dicor 501 for the vents that I installed on our current camper.

That said, I used Dicor 501 for the vents that I installed on our current camper.

I've used the 5200 by 3M but not sure I'd use it in this application. I used 5200 when I installed the stainless steel Guardian plates on my coach slide rooms and it glued and sealed them on perfectly. It's a great adhesive and was the recommended adhesive by the vendor, but Dicor works so well as a lap sealant I don't know why one would veer away from it.

While I'm guilty of trying different chemicals and/or processes at times on various projects, there are those that are the industry standard that work so well I see no sense in taking chances.

I see all too often the opposite side when an industry standard is ignored and the project goes off the rails that I am less inclined to gamble with unknowns or experiment. Many times these "detours" are taken to save money as the standard costs a little more, but unfortunately end up costing far more in the long run than had the proper product been used. At the cost of about $15 for a tube of Dicor, it just doesn't add up. The juice ain't worth the squeeze. ;)


Mike, I defer to you.

I was unfamiliar with Dicor. I will buy some for my next project. Thank you!

I'm merely staying that I would prefer to stick with something I'm familiar with and I'm less inclined to recommend something that I personally have not used. Again, not saying that it wouldn't work, it's just not it's intended purpose.

A heat gun makes short work of dicor as well. I didn’t know it would work with 5200. That’s good stuff. I’ve used in on both carpet screw snaps and though hull fittings. Works very well.

Dicor on the RV roof for me. So much so that I still don’t understand why someone would use eternabond tape on an RV roof. I guess if it’s separating real bad, but that’s another issue.

Didn't get much done last week as it was a roller coaster of a ride.

Saturday I was able to hang out with my grandson all day as the wife and I were able to watch him all day. He hung out with me in the shop while I did a few tasks.

I had purchased some new fire extinguishers for the shop and house a couple of weeks ago and they arrived last week but I didn't have time to hang them. My old ones were getting quite old and were borderline needing to be recharged as well as time for another hydrostatic test on them. It was almost as much as new ones, so I bit the bullet and bought some new ones for the shop and another one for the house as well as a new replacement one for the coach.

My grandson helped me hang them around the shop. One near the man door.

One on the lift column.

One back at the machining area, on the lathe.

fire4.jpg

I also have one on the oxy/acetylene torch rig.
fire5.jpg

Another near the door to the RV/storage bay.

My grandson then helped me by holding the flashlight while I finished installing the power supply and router for our Starlink in the coach.

Next he helped me rip the carpet from the box enclosure in the bedroom. My wife thought it would look nice if I matched this box enclosure to the one in the bathroom that I just recovered.

That was about all that was done in the shop last week.

Then Sunday morning I was able to sit on the deck with a cup or four of coffee and relax and breathe a sigh of relief from the events of last week.

I was wondering what I would do with the old fire extinguishers if I got new ones for the barn. Did you put the old ones in different places (looks like the cutting torch tanks got an old one) or disposing them?

Last week was a roller coaster of a ride as our granddaughter decided to come a little early. My DIL had a weekly checkup early last week and during the stress test, her doctor didn't like the results so thought it best to deliver our granddaughter a few weeks early. Both her and my DIL had a rough couple of days, but my son was finally able to bring his lovely wife and his beautiful daughter home late Saturday afternoon. We had our grandson so he could take care of getting his family home and then we were able to go over and both my wife and I were able to hold our granddaughter, Ruby, for the first time.

It was hard seeing that sweet little angel hooked up to all of the tubes and wires. It stirred up emotions, memories and feelings that I have tried for nearly 35 years to bury down deep. My son was so sweet with her and it made me so proud, but I was a complete mess all week.

She was a couple of days old before my son was able to hold her, but watching him was so impactful and one of my proudest moments.

I had to get her on the doorframe next to her brother's markings.

The drive home.

Home at last.

Saturday evening my wife and I went to visit and bring our grandson home and my wife and I were able to hold our granddaughter for the first time.

And she was able to meet her big brother.

I feel so blessed with everything that transpired last week as we welcomed this little angel into our family and into the world. The Lord has truly blessed me and my family this past week, despite the bumpy first few days.

The two older ones were still charged. The one on the oxy/acetylene setup was purchased new in 2017 when I first built the shop, the other one near the RV/storage bay door is about 20+ years old and still has a charge so it was kept as a backup. The other three were disposed as they were needing to be hydrostatic tested again and were all showing that they needed to be charged.

Yesterday after my morning coffee on the deck and in between cloud bursts of rain, I was able to get the box enclosure of the bedroom in the coach knocked out.

Vertical pieced ripped down to size and then cut to length and mocked in place.

Then the top horizontal piece followed.
coach4.jpg

Once I was pleased with the fitment, I glued them in place and cut the corner molding to length.
coach5.jpg

After sanding the corner trim I was able to get a few coats of stain on it before closing up for the day.
coach6.jpg


I just put the table saw away and the sky opened up again so the timing was perfect. I need to put a few coats of clear on the trim piece, then it can be installed and the interior of the coach should be done for the season.

The wife was meal prepping for the week and made a couple of meals to drop off to my son and his family so we were able to go see them again last night and I was able to hold my granddaughter again and play with my grandson for a bit.

Your wife has a good eye.

All my mom's worries about the timing of a grandchild melted away the first time that she held him.

A guy who worked for one of the local extinguisher services told me that the main reason why the annual inspections for fire extinguishers is that the powder sits in the bottom of the bottle and being a very fine 'silt' that it slowly compacts until it's so firm that it won't discharge. He said that just the subtle vibrations in a building can do it if given enough time. The real reason why they discharge them and then re-fill and recharge them is to break up that compacting. Since being told that I've made a point of installing the extinguishers in vehicles so that I can invert them from time to time. Most are laid on their sides, so I make it so that I can easily swap them end for end or roll them over 180° When one catches my eye and I can't recall when I last inverted it I do so then. With no data whatsoever to support it I estimate that occurs roughly every quarter to bi-annually depending on how often that particular vehicle is driven.
My shop extinguisher is a wet one. Pressurized water with a fire extinguishing agent mixed into the water.

Thanks Thom.

Yes, inverting the ABC fire extinguishers is something I teach our Operation's Supervisors for when they are performing their monthly inspections. Unfortunately, I think only a few actually perform this procedure, but we have to have them inspected annually by a 3rd party so I know they're getting done at least once a year.

In my home shop I generally grab the fire extinguishers at least once a month and invert them while wandering around the shop. It only takes a matter of a couple of minutes so there's no reason not to.

Congrats! Glad to hear everyone is doing well.

Congrats on your new addition to the family Mike!

Thanks Marc and Vincent. It was a rough few days last week between baby and momma having some unexpected issues. The Lord definitely was watching over my family and we were able to bring everyone home safe and sound.

Thank you.

Congratulations, Mike.

Also, great job on the fire extinguishers.

Having been party to two machine shop fires (both involving lathes and turning exotic alloys based on Magnesium and Titanium), having the safety equipment is essential.

His includes the right type of fire extinguisher……

(Class D).

Thank you.

While I don't necessarily work with the exotics that require a Class D extinguisher, just having extinguishers placed in proper locations is paramount to be able to quickly access them when or if the need arises. I had one fire back when I was working on a 1967 C-10, the one I traded for, restored and then sold to buy my wife's engagement ring in 1988. I was cutting a cab corner out and didn't realize that the previous owner had stuffed a magazine down under the seat in which caught fire and forced me to quickly grab a fire extinguisher to put it out. Due to following the 7 P's (Proper Prior Planning Prevents Piss Poor Performance) I had an extinguisher within reaching distance and quickly was able to put it out before any additional damage other than the magazine itself and some smoke inside the cab.

My dad didn't have fire extinguishers around the farm, but fortunately I had recently started my career working as an Industrial Maintenance Mechanic just prior to this and during my safety and orientation training, fire extinguisher training was heavily discussed so I had bought one to keep in my little workshop on my parent's farm. Had it not been for that, I am confident that the truck as well as the shop on my parent's farm would have been consumed.


During my career, we have had 2 fires in our Industrial Maintenance Department shop over the course of the nearly 38 years I've been a mechanic and both times the mechanic was able to quickly grab a fire extinguisher and extinguish the fire before it spread and resulted in more damage or loss. The worst outcome from both were a mess to clean up from the extinguisher itself, but both could have been much worse had there not been an extinguisher readily available. This is a topic I cover in depth during onboarding new mechanics into our department, especially when they think that the preliminary safety training is a waste of time.


I have been waffling on updating my extinguishers over the past several months as they were needing to be hydrostatically tested again, this is required every 12-years and all had already been tested a couple of time prior. However, this time I had noticed a couple were also needing to be recharged. I have also noticed several people that I follow on YouTube and IG that have either had a fire in their workshop or they had someone close to them have a fire and each one were total losses, which made me decide to pull the trigger and update them sooner rather than later.

I have a few rules in my shop when it comes to welding in my home shop, such as I do not weld on anything within about 45-60 minutes of closing the shop for the night and I also look the area over closely and remove anything that can potentially catch fire prior and if anything seems higher than normal risk, I have a fire watcher, such as my son or wife while I perform the welding. I seldom need the latter, but there have been a few times when I have felt just a little more comfortable resorting to such measures.

Kickass Mike!, congratulations to everyone. With both of us having experienced a premi, buddy I certainly understand what you were going through. Thankfully everything turned out great.

Thanks Cam. Yeah, it stirred up a lot of emotion and memories I have fought to keep buried for many years. Funny how quickly they resurface.

One of the guys that service our extinguishers at work told me to turn my older ones at home upside and give them a few decent smacks with plastic dead blow hammer to dislodge any compacted media.

If they've been sitting for a while without inverting yes, but if you make it a habit to invert them several times a year the dead blow shouldn't be necessary. You can usually feel the powder shift internally when inverting. Grab one that hasn't been inverted in many years and you can tell the difference, that's when the dead blow procedure may be worthwhile.

Congrats on the new granddaughter! Our #6 grand was about 4 weeks early, 4lbs - 10oz 17", spent 4 weeks in the NICU. He was mom & dads first and they were a wreck for awhile. Today, Westley is doing great. He will be crawling soon enough and getting into everything.

Congrats on the new grand daughter.
Funny, I always look at the background of your (and others) pics. In the post before you announced the arrival of Ruby I noticed the height markings on the door casing.
