OK... so then most non SPI epoxy primers should be just fine with the 120 grit???
I'm thinking about 2 wet coats of epoxy, guide coat, block with 220, then finish up 320, 400 wet, 600 wet then tack it off and top coat.
Is that a plan? Or am I thinking the wrong way about this?
The parts had very nice paint on them and no bodywork needed, but I'm painting them black and want the primer to be super flat.
Open to any and all suggestions
