I could use some primer advice. I completed all the sheet metal work with rust areas out and new metal in areas. Next, I plan to start body filler. However, I don’t have time to work on the entire car at one time. I want to do each section or panel at different times. My question is what primer I should use directly over the bare metal and body filler that will protect the surface is for several months or more before I move to high build primer/block sanding portion? Etching primer, a sealer primer, high build primer?? I know the high build primer is porous and may allow moisture to get in? The car is in a garage.
Thanks for any help.
Your going to want to use an epoxy primer on all bare metal areas. Filler can be applied over the epoxy, I always give it a little scuff before putting any filler on. Then use your 2k high build after the filler.
