MashaAllah Your car is truly a white fairy, in the above workshop pictures your car was truly sparkling and glistening.
The matt black paint job done too is flawless and meticulous, especially the work that was put into the masking. Because over sprays are a real PIA to remove.
But one thing, why didnt you simply get a matt black wrap on the bumper?? This way you'll have the option to go back to the original paint any time you want and it save you the hassle of a paint job?
