Well the Turtle Wax Ice was tried on two of my cars, 93 Aerostar Black, 95 Caprice White. Paint on both cars was in good shape, I do take care of them. I figured after posting I would give the product the benefit of the doubt. The Aerostar got 2 coats in fact. The shine was OK for a little while, the water on the roofs and hoods of both cars no longer beads water, that stopped in about 2 weeks.
I will burn up the rest of it on the black plastic/rubber parts of the cars, (it looks good on those parts). I won't use it on the paint anymore, I think someone else mentioned that.
I ended up washing the black Aerostar a few times with dish soap, and applying Liquid Glass. IMO the Liquid Glass is way better than the Turtle Wax Ice!
