My boyfriend is a retired body man after 30 years, all he uses and swears by is WIZARD products. This cannot be applied by hand, It must be buffed with a buffer. I can tell you this, that stuff is like magic. He buffed out my 90 Lumina last summer, and it's all original paint and clear coat (torch red). It is a two step process, first step is Wizard rough cut, and second step is Wizard finish cut.

Adam's Polish does work good, but you'll be an old man by the time you get it done.....Too much manual labor for me, learn to use a buffer
