I got the grills repainted last week. I used Eastwood’s paint: Charcoal gray, Silver/Argent, and under hood matte black. I then clear coated with a satin finish.
Before paint, I sanded and cleaned real well. I sprayed a couple light coats of Bulldog® Adhesion Promoter and then sprayed with high build primer. Sanded it all down again with 600 grit. I painted the silver first and then waited a few days before masking off the silver with some 1/4 tape. I then painted the black. Masked it off before painting the charcoal.
