I've thought about buying Black Velvet or something along those lines. Last time I waxed the car I used Turtle Wax ICE, but I hate how the dealer scratched the clear when they let a 16 year old detail my car.

What you guys recommend to buff out scratches and wax a black car with?

 

Depends how bad the scratches are. If they're very minimal, I've had luck using ssr2 by hand for swirls. You can always do red moose glaze followed by nattys blue paste wax. Its a very tested and true combo for achieving a deep gloss on black vehicles.

does the glaze and the wax actually repair the swirls, or just covers them up
