Woolwax Spray Gun - Thinner Cavity Wands?

[Spta97]

I recently had a rear Upper Control Arm failure and wanted to use a lanolin-based undercoating to slow down the rust on my 16 year old Nissan Armada.

After a ton of research I went with Surface Shield and the Woolwax gun:

https://www.amazon.com/dp/B0070WTGZG/?tag=atomicindus08-20

It worked out great, however the flex wands are too large in diameter to fit into doors (great for frame rails).

Woolwax does not make a thinner hose - so I am either stuck buying the cans (I have 3.5 gallons of my bucket left) at $10/per and a cavity wand like this: https://www.amazon.com/gp/product/B0BQ3B1GNF/?tag=atomicindus08-20 or trying to make a thinner hose which will fit.

I did get the cans and that cavity wand so I can finish the doors/hatch but really would prefer to do it all with my compressor.

Can anyone offer any advice on making a thinner hose with a 360 spray tip? Not sure what material it is but need something semi-firm and then a 360 spray tip with a barb to go on the end.

This vid shows exactly what I want but he doesn't say the gun name...also since I bought the Woolwax already would like to modify that rather than buying a new one.

Thanks!

The gun I have it shown in here:

The cavity tip is really small and works well.

 

[Spta97]

Thanks for posting that and good vid! Although that gun (wands) are exactly what I am looking for, it seems to be a Canadian company and not sure if they will ship here (also would like to see if I can leverage my existing gun). Not to be cheap, but I'll only use this once a year on two vehicles.

Per an Amazon question, Woolwax said there are no thinner hoses because they can't take the pressure. Not sure why that is as other companies (like the one you referenced) have them.

I use fluid film and their sprayer. I tried some smaller hose and it didn't work. Doors or quarter panels I would drill some holes and install body plugs after spraying. Or slightly disassemble to spray.

 

[plinker]

From the limited research I've done Woolwax is supposedly thicker then Fluid film, I cant tell much difference, though the gallon can of Fluid film I have is a couple years old and the Woolwax at work is recent.

I did find these straws/nozzles on ebay for Fluid film spray cans, I was debating on ordering a pair to try.

I did the truck last fall with woolwax aerosol.

The wand seemed to work fine, though I did not do inside the door panels. Is there a plug you can remove?

Thanks. Drilling holes is not something I am comfortable with but I know places like Krown do that.

To be clear m using Surface Shield which is actually thinner than FF.

I’ve got some of the spray can extensions on order but hoping to avoid cans if I can.

I’ll have to look into plugs thanks. If not I may be forced to use the spray cans for the doors as many people do.

I’d imagine that one can should be plenty for the doors but seeing that vid I also want to make sure I get inside the fenders and quarter panels - that may require more.

3m makes thin wands for their aerosol cavity wax. https://www.3m.com/3M/en_US/p/d/b40066669/.

Interesting that 3M makes a cavity wax, but all of their undercoating's are rubberized.

I used aerosol Surface shield on our 2009 fresh from florida Honda Fit last year, and based on that experience I don't feel like the cans would do a good job of 360* coverage using a long wand or tube. IMHO surface shield IN A CAN is either meant to be sprayed through the short red straw that always falls off, or direct from the nozzle. I did warm up the surface shield as well before application. YMMV

With that being said, although I only have a smaller pancake compressor I do want to get an undercoating gun w/ cavity wand and do my frame rails and other underbody areas.

Thanks for the info - disappointed to hear though.

If that is the case it seems I may have to get a new gun which includes the skinny wands if I can’t find a way to mod this one.

I am in the same boat as you as I have the same "pro" gun. If I find a solution I will post my ideas and pictures as I also don't want to buy spray cans when I have gallons of product on hand. Additionally, I heat Fluid Film and Wool Wax in a hot water bath before application, and it can be thinned with vegetable oil.

 

[zak77]

Don't waste your time or money on the spray cans. I used those for a couple years on my truck and was always surprised how fast it disappeared until i used FF out of the gallon with a spray gun. Over a year later it's still coated w/FF. I am also on the hunt for nozzles that can be attached to a spray gun to get to tight areas w/FF so i was hoping to find an answer here but no such luck. I tried a length of hose on the end of the spray gun but wasnt happy with how it sprayed out. If i come across something that works, i'll pass the info along.

That would be great thank you.

The nice thing about Surface Shield is it is thinner than both FF and WW but is durable (according to repair geek on YouTube).

When I sprayed it was 70 and sunny and I had no issues. My next spray will be in November so we’ll see if it’s the same when it’s colder.

Have a look at KBS schutz underseal spray gun.

Yea I got the 5 gallon and really want to avoid spray cans. When I was quoted having a shop do it they said $450 for the initial coat. So I’m still ahead of the game and if I get another spray gun eventually it will pay for itself.

I really don’t want to though but seems I can get one with smaller wands in the $200-$350 range.

Thanks but this seems to have the same diameter hose as the Woolwax gun (from what I can tell from the pics).

You’re doing a great job of remaining calm as the whole forum displays their lack of reading comprehension

The huge straws always bothered me, too. I’m used to 3M and SEM cavity wax with the 1/8” straws. If you find a skinny straw that’s compatible with the gun I’ll be in line right behind you.

And yes the schutz gun is also huge straws

Ha ha! Thank you I’m known for my composure lol.

Other than the lack of a thin wand, the WW gun worked excellent. Though I’m not sure why a thin wand isn’t an option.

FroM the replies I may have to get another gun for the doors and cavities. Grrr.

Not sure either...I haven't had any issues and I just run standard 90psi line pressure with this and don't thin or heat my fluid film at all, sprays perfectly fine.

Pro-tip: those body plugs are actually free at the u-pull junkyards. As long as you wear pants with pockets.

Sorry, no way I’m drilling holes in my vehicle:!

Not that it matters, but you are kind of only doing half the job if you only spray the exterior and what the terrible wand thing can do. The majority of the problems are going to start from the inside out.

At Krown, for example, the **** is very high pressure. It's almost like a fogging oil spray. I say that because the pressure you are going to be able to spray the surface shield at isn't going to be much help. It's too thick.

Again, the holes are going to have any effect on structural integrity nor will they pose any kind of rust problem themselves. You just put some white lithium grease or paint over the newly created bare metal.

Krown is a great product. Best rust proofing out there IMHO.

I get that some people dont want to drill but there are a few internal places where you really cant get to on some vehicles even if you remove trim pieces and use existing plugs and holes.

That’s a fair point and I don’t disagree. However, if you watch the video I posted you can see on the truck he is working on he manages to get into internal cavities by removing stuff.

I would rather go that route than risk hitting some wires or something. The truck is 16 years old and I’ve had other mechanical issues so want to minimize risk.

I figure with the right wand I can get into the interior cavities.

The OEM punched thousands of holes in it already.

What are you losing? A tiny bit of e-coat? E-coat that you clearly don’t trust since you’re now rustproofing the car yourself?

Where are you located? Woolwax is $175-200 for a vehicle locally (Midwest) - not sure if there's that much difference between retailers?

 

[Jeepster04]

The bigger hose is needed for air flow. The gun is a venturi and needs the high flow of air to pull the WW out of the container. Smaller hose wont allow enough air to flow to get the pressure differential.

Eric O must be using a different type of gun. It looks like it pressurizes the canister to push the media out.

 

[Hohn]

I did Surface Shield with the Woolwax gun on my GX460 right after I bought it. I still smell like a sheep farm.

Tagging this thread to follow.

In NY. Everything is WAY more expensive. I’m happy I did it myself though. Just wish I had a lift!

Thank you for this post as now everything finally makes sense! You are correct in that the guns which had small hoses all had metal cans and I assume were pressurized.

I think that is what I’ll have to do - get a new gun specifically for the cavities/doors. Seems the minimum is $200 but open to recommendations!

I only did the SS and hit a lot of the exhaust by mistake. When I took it for a ride it was a real smoke show lol.

However, after 10 min it stopped and I can only faintly smell it when I was outside of the truck (and only for a day or so).

I read the WW smells much worse than SS.

I’m debating between the two as the Amazon one had some reported issues but also a lot more reviews.

Works fine for me, sprays fluid film undulated at coolish ambient temps without issue.

The Amazon one is no longer in stock so I went with the TP Tools one I linked above.

Will post an update once I had a chance to use.

One final question - I don't empty/clean my Woolwax gun (using Surface Shield). Will this be any different for the pressurized gun or can I just keep the SS in it?

Pretty sure thats the Dominion Sure Seal gun, same as I have. Its a good one. If you want to do a pickup bedside from the tail light u should order or make a long wand
