Well after more pinhole chasing & sanding with the DZ3 than I care to think about I finally got to shoot the PPG DP48LF epoxy primer. This is the primer of choice for all my paint work be it a rigger or 1/8 scale. Absolutely tough as nails & a superb base for your topcoat colors. Normally you do not sand this primer before top coating but since we're going for that mirror finish I will hit this with 600 wet once before the yellow & purple pearl are applied.
