UPol-Raptor urethane undercoating is what I like, 4 qt bottles in a kit, some kits come with the shultz gun. Also comes in a tintable version, I add extra urethane paint and reducer on the top side for a smoother finish, but not as glossy as paint alone, thinner version put on metal or plastic, with HVLP GUN 1.8 tip after mixing well.
