Coarse cloth???

UGH!!!!!!!!!!
Not on a new paint job man...
The coarse cloth would help with oxidized paint jobs in where you're removing dead 'skin'...
I use Turtle Wax's 'Express Shine'... ONE step, carnauba based wax..
It's superb...quick and easy....Leaves a super smooth...almost like plastic coating on the paint that really brings out the metal flake...and lasts quite a while....
