I've seen guys at car shows using this stuff called Hand Glaze made by 3M. Does anyone here use it? What is it's general pourpose. Usually I wax it with Maguires gold class, and at shows I just use a detailer spray wax for touch ups. I have a custom Spies Hecker paint job, so i'm pretty picky about what I put on it. Let me know if this 3M stuff is any good.
