I think I’ll go over the sandblasted frame with 80 grit since it’s been about a week since I’ve blasted it. Then I’ll blow it off, clean it with wax & grease remover, then apply the Valspar epoxy primer. I’m not going to use metal prep because the metal prep doesn’t recommend using it on a sandblasted metal because it’ll rust instantaneously.

I’ve used POR 15 on other projects. It’s good stuff.
Thanks guy’s
