Paint advice needed

Thank you. Did you spray the epoxy primer directly over the prepped original finish, or did you completely strip it down to bare metal?


That's what I'm figuring. Heck, when we painted my dad's Ranchero years back, we used rattle can primer as we body-worked panel by panel. Then, the paint shop sprayed over that. It looks the same as it did the day it was sprayed 25 years ago.

Do you have idea what type of paint these cars had originally? Was it an acrylic enamel?
I sanded everything down not completely to bare metal but mostly. The there was some old primer left. I would sand it down at least to primer. There was a couple spots like the hood hinges that I sprayed over the old paint without sanding and it is peeling already. Spi has a spec on what the preped surface should be sanded too but I can't recall off the top of my head.
