Yesterday I detailed a Corvette that get's washed by some mobile guy once per week who supposedly uses a waterless dri-wash...the behicle owner sais he uses about 1/4 of a small spray bottle to spray and wipe the car clean. I told him his car looked like it...I should have asked him if the guy also throws a little sand in the mix for extra cleaning power, cause it was HAMMERED. Though I've never used this stuff, it's gotta be absolute junk. Right?
