more than one coat

[bjmill81]

Ok Im new to powder coating, and have many questions. Im having problems applying two coats Ive been fully curing the first coat and shooting the secound coat hot. but when I apply the secound coat the powder melts to fast or it doesnt stick and I end up with dull spots and its feels like sandpaper. I also been useing schotch brite on the first coat and using paint thinner to clean. I have a craftsman gun would the be the problem? because Ive been reading that a secound coat should be applied with low votts.

I also have a harbor fright gun would that be better on 2nd coats?

How hot? but when I apply the secound coat the powder melts to fast or it doesnt stick and I end up with dull spots and its feels like sandpaper. Try applying a little more powder and be sure you have a good ground

I also been useing schotch brite on the first coat and using paint thinner to clean. Don't clean with anything petroleum based

Try cleaning with Acetone or a pre-paint cleaner from your local paint supply store.
