number of "coats" of paint

Number of passes for basecoat = til it covers. Viper Red, = 3/4 of a high solid ultra red magenta, covers easy. Had a Chevy Blue Metallic once, transparent as hell and took 7 coats to cover (barely). Bottom line, it takes as many coats as it takes to achieve uniform, and complete coverage. Clear is a different story, most high solid clears = 2-3 coats max.
