Paul, I was going to ask Craig a similar question but not exactly. Yes, you can use a powder primer and then apply the top coats, at least some folks can. I have tried it and didn't have the best luck, same with clear coat powders, I haven't mastered that process either. I think the secret probably lies in the equipment you have to apply the powder. I use a dual voltage gun from Eastwood and its not a real quality piece of equipment compared to what powder coating shops use I'm sure. My results when applying more than one coat are less than stellar so i try not to have to do it. I don't think the thickness of the part has anything to do do with it because even with a primer on the parts my gun will jump a spark through the primer coat the same as to bare metal, the second coat just doesn't seem to adhere as well (the dry powder) to the base coat or won't cure to the same gloss as a single coat will. The primers I have came from the same place as the colored powder so that shouldn't have been the issue. I'm sure it's operator error, I just don't know what the error was.....GB
