So recently there’s been a discussion here about priming some fresh blasted metal. The one side and manufacture tech sheet says to commercial blast the metal and prime the fresh blasted texture surface. The other side says to 80 grit sand the blasting texture down to a smoother surface then prime it. The reasoning here is that it’s nearly impossible to wipe down the surface with any solvents, remove finger prints, or anything that may be stuck in the texture. So the second position here makes more sense, involves a shit load more labor and violates the tech sheet. What’s the best way?
