I am a novice at powder coating. I just bought a small powder coating system from Caswell. Also I bought black polyester powder. I sandblasted my first few pieces and coated them. Cured for 20 Min at 375 degrees. Pulled them out and let cool. Coating does not seem tough--they scratch easily. Am I doing something wrong? Do I need to use different type of powder? Is there some product for filling in rust pits on older material?
Thanks

Lato,
Sounds like the powder is under cured. You want the BMT base metal temp at 375 before you start timing.
Caswell has Lab-Metal, works great for filling defects.
IMHO

Is it scratching through the coating or just marring the finish?

it is scratching all the way through to the metal, thanks jamey

Then the part is under cured. Try setting the oven on 400 and cure for 30 min. The best and safest way is to use a infared temp gun for getting accurate temps on the part.

I've got some of it, and have been happy with the results so far. It's not for structural repairs, but for filling pits, I think you'll like it.
