Doug, I had no clue that pro paint is not just paint. I suppose they paint cars the same way. This morning I rattle canned primer on the frame. It has baked in the truck all day to speed up the cure process. It may or may not make a difference. Shot the bare metal with Rustoleum rusty metal primer, then shot over that with white primer. Color goes on tomorrow morning. Once my daughter sees it and gives thumbs up or down, she will apply the last 2 coats to "make it her own". It is bathroom tile pink. Once it dries she will then take a paint brush to it and do her art stuff on the frame.
