So the other day at work there were some guys doing a promotion on fast wax. They cleaned my headlights and it took off all the hazy crusty junk. I was automatically sold and bought 3 cans.
I just did the whole car, so I'll update pics later. This stuff is awesome though.
If it's the waterless wash gimmick, here's the issue I have.
Take a look at this sand from Pismo Beach, if you're not rinsing off the small granules, you do the math. Kinda like sandpaper. Take a handful of sand and rub it on metal or plastic, then think about your clearcoat
