Epoxy primer = nice new layer to build from
2K primer = level to make sure surface is flat. Will stick to new epoxy
Epoxy primer as sealer = nice coat for paint to stick to, seals over potential different surfaces in the 2K primer as you sand to make it flat
Base = color layer
Clear = extra cost, but level of paint you can sand for flat finish and buff to a shine
---OR---
Hot Rod Black = Great paint but it took a quart just to do my 74 Satellite hood. Like someone said, it is a bear to get even coats. I have only painted 3 cars so I am still a rookie, but that Hot Rod Black was a PITA.
