I am currentlt doing a frame up restoration on a 1974 f-250 high boy. I have completed the chassis. I sandblasted frame and painted, cleaned and replaced everything. 360 has been rebuilt and installed and I am now working on the body work. I am installing a 1971 body on the 74 chassis. I am painting it in pieces and installing as I go. Two days ago I shot the cab inside and out. This is my first time using base clear. I sanded to bare metal, osphoed, did bodywork(minor dings, no rust), used ful-pox metal etching primer, 3 coats nason 2k primer, wetsanded with 400 grit, did more bodywork as needed then shot 2 more coats 2k primer. I then wet sanded from 400 to 600. I am also using nason base and clear with medium reducer. I am very pleased with cab, orange peel comparable to a new car. I did get a heavy run and sag on the cowl. Because I cut through to the primer in one place while wetsanding. I have decided to repaint the cowl. I have wet sanded back to 600 grit, however i did not go back to primer. My question is will it be ok to repaint over existing top coat and if so how long should I wait to re-shoot it? Any help and advice would be greatly appreciated.

 

I've used Nason paint. It's a budget paint (owned by Dupont) but I've been very satisfied with it. Since it's b/c, I assume you used the hardenders per the label directions. It should be safe to repaint it the next day.

The one difference between paints like Nason, and the premium paints like Dupont's Chromabase, is that Nason seems to be a little slower curing. But if you used the hardeners, it should be fine to recoat anytime you want. Don't worry about using a sealer between them. (IMO)

I agree with Marc 100%. Clearcoat makes an excellent sealer. Sand, clean, redo the base, and reclear.
