Currently, I am polishing my black 4runner. I am using PC 7424 with lake country yellow, orange, and white pads. I am using Manzerna 91e(IP), 85r, Klasse AIO, Klasse Sealant, & Pinnacle Souveran Wax. So far the results are incredible, although, I noticed before and after the polish that the black paint isn't as deep as I am used to on a black vehicle. I cleaned the paint with a cleaner but it still doesn't have that super deep black look. It looks great and maybe I am being to judgmental, but I was wondering if the 4Runner is a single stage paint or if it has a clear coat before I try polishing it again. Your help is greatly appreciated.
