I either use acetone or laquer thinner to clean with. It dries quick and doesn't leave any residue. That's what I found to work best for me. As for the chipping, undercuring will definitely cause that. When I first bought my PC gun, I didn't have an oven, so I used a heat gun. I cured it only until the PC flowed out. It chipped worse than nail polish. Make sure you cure it correctly, and it will be a lot more durable.

should i wash the parts with alcohol or just rinse with water? my oven now gets to around 400 degrees, so i think youre probably right about undercuring.. any other good solutions to clean or rinse parts? thanksLeave a comment:

Wash the part after blasting, but the real problem sounds like undercuring.
However keep in mind powder isn't bullit proof. It's just tough.Leave a comment:

chipping
no, i used sandblasting sand. i blew the part off real good before trying to coat, maybe i need to wipe down or rinse with alcohol first? i know that powder coating is supposed to be very hard when finished, so any thoughts are appreciated..Leave a comment:

Guest replieddid you blast it with aluminum oxide to get a good surface for the powder to stick ? i don't use prime so far never had any problemsLeave a comment:

chipping
i just started powdercoating and noticed on my first try that the coating chipped real easy. is this because i didnt get it hot enough to cure right or in my surface prep? my oven at first only got to around 325 degrees, which is at the low end. does anybody use a primer or base coat to help bonding and reduce chipping? thanks
