Whats the best way to reduce scratches when washing/drying black sapphire metallic? So far I've considered getting a foam cannon setup (expensive but do-able), ONR bucket, ONR plus pressure washer or upgrading my 2 bucket wash mits/materials with a garden hose.
I live in socal and usually have to deal with hard water and washing with some sort of sun on the car. Car has been ceramic coated.
