Anyone ever heard of "dry wash 'n guard"? It is a waterless carwash a protectant. You are supposedly able to use it on a dirty vehicle without scratching the paint, because it contains special polymers. I wouldn't even think about trying that, although I'm sure it is possible. Anyways I use it as a "quick" wax. Way better then spray wax. It will actually make a dull finnish look good and lasts several months. The best part is I can do my H3 in the garage by my self in about an hour. I would suggest people look into it. I don't want to sound like a commercial, but there may be info online. Possibly a web site, but I have never checked.
Anyways, I use it on all my vehicles after I get a good base of carnuba "Mag. Gold" down. Lets just say they never look like they need waxed. They all look showroom new.
