Powder coating question

I sprayed down a sandblasted part after cleaning it and stuck it in the oven.. it came out great, except I missed one very well hidden spot, and another spot has a bump in it from something.. can I sand down the bump, wipe it down with acetone, and then re-spray the one spot and the other spot i missed?

Are you sure you mean powder coating and not normal spray painting or have you got one of the little Caswell / Eastwood hobby guns at home or something?

99% of the time it's fine to shoot powder over powder, although you may want to pull your KV's down a little (sub 60) and pre-heat the part and shoot it whilst it's hot to get better adhesion.

This ^^^ at the shop I worked at, I had my motorcycle frame painted with 3 coats total. It is perfectly fine to shoot powder over powder again. My frame was first thrown in the over for a few minutes to warm up, the powder was shot in the hard to get spots then it got its first coat. Then it went in to bake, after that it got its second coat. After that was baked, and cooled, it got the clear coat.

Fair enough then, crack on!


Like I said though, some powders are funny and don't like being shot over an existing coat hence a lot of people hotflock candy powders.
If you do find yourself having problems with it not sticking, match the PMT to just under the flow out temperature and you should be laughing then.
