have anyone ever used any klasse detailing products? my parents pulled some "klasse all in one" that says it will remove oxidzed paint, old wax build up, road tar, surface scratches, swirl marks, gas and insect stains.i was wondering if anyone has tried these products. i also have a klasse high gloss sealeant glaze that says you put it on top of the all in one. i might try this stuff on my truck tomorrow. has anyone ever used this stuff or heard of it?
