Have you guys seen this stuff? It comes in a spray bottle, you spray on a mist, let sit for a few seconds, then use a microfiber towel to wipe off and buff to a shine. I saw it at the autoparts store, and a guy I work with uses it on his Infinity, but to me it is just WRONG! The dirt will scratch the paint....right?? Is this stuff a con or does it actually work?
