Powder Coating question

[jaysonb]

If I was to have an old tool box blasted and powder coated, and there were dents in the box that you couldn't hammer out because of the box being double wall, is there a filler that powder coat will work with?

 

[BHH]

Can you use a slide hammer to get them out? Maybe this is taking it to the extreme...

if they are small dings, I use JB Weld original red/white formula, not the quick dry version, it sands great, bakes no issues and will spread decently with a stiff card if you want to float with it.

If they are small as said before powdercoat suppliers make a filler that goes on just like the powder cure it and sand it. Or you can purchase a product called all metal or hi temp all metal that is designed to work with powdercoat. Comes out of can ready to use also will not shrink up on you.

Try welding a small tab with a Mig in the very center of the dent. Use a small slide hammer or prying arm to lift the dent. You can then then use a small bumping hammer and file/low speed andle die grinder with 120 grit disc to finish out the dent before you use All metal or JB Weld. If the dent is of any size, work in a circular/spiral pattern from the outside in, this will reduce the stretching of the metal

jb weld will melt down at 350 in an oven..... I use a product called all metal for parts that have a lot of corrosion. After using the all metal I sand smooth put a thick primer coat on of powder then apply top coat and clear coat good luck

JB Weld will not melt down at 350F . It is used all the time in powder coating, where cure temps are 400f, as a cheap alternative to welding the dings. I use a product from tiger-Drylac called EpoStrong. Its an epoxy filler made specifically for powder coating and works just like bondo but wont shrink and pop in the oven like standard bondo. All Metal works but is very expensive for the ammount you get and canwithstand 350F but can go to 420 for a max 20 minutes to powdercoat. Hi Temp Lab Metal is for multiple heat cycles and can withstand 1000F and works well also but again very expensive for the amount you get.The downside to the HighTemp Lab Metal is that it needs to be applied and then air dry for 24 hours before an oven cure for an hour before you can work it.

respectfully have to say yer' speakin incorrect data, I do a lot of custom tins and they always need small ding and dent repair, in other words, I use it a lot and prefer its workability over lab metal in a can.

Never tried the JB weld is it that much easier to work with than lab metal. I do this on the side to enable my tool addiction Seriously how easy is the Jb weld to work with. I have a customer bringing me a tool box he wants me to do.

 

[o1marc]

The workability of LabMetal can be adjusted by using thinner to thin it out to what ever consistancy works for you. You cant do that as much with the JB weld. I didnt like the first time I used the LabMetal because it was too liquid and the spot you were filling had to be upright or the stuff would just flow off. Both can be oven cured to speed the drying process for you to start working it.

float it out and be happy, I always prep via media blasting, the wiping with acetone, mix it up right on the box or tank and spread it around with a stiff card, a little goes a long way so dont mix to much, can always do multiple skim layers, dries faster and no shrinkage...and be quick . let it sit and then sand hell out of it with a power sander to knock the high spots and ridges from spreading and wet sand to what makes you happy. I sand in stages and ending with 600 or so.

Epo strong is this less expensive than lab metal and how big is the container. I am used to using lab metal but might try epo strong or jb weld just to see the difference thanks for any info you might have.

 

[o1marc]

Th EpoStrong runs about $70, but you get a 2lb can of putty and a 1lb can of hardener. So it goes a long way. If you need filler often it is the way to go. I used a lot of it converting these rare mercury valve covers:

Nice job on the Merc valve covers I will have to order some of the Epo strog and give it a try. You would not happen to have a link for it would you thamks.

EpoStrong is the 3rd from last item on this download list. You'll need to order it from the Midwest location in Ill.
