I now have (3) coats of SG on the car and will continue to add coats till I get some Griots Carnauba Wax to top it, but by then, the cars finish is going to be illegal due to its increased drag coefficient, thus giving me a couple tickets! This product is sooooooo easy to use making it a "no brainer", especially if you've got a black car. I'd actually like to detail a black car with this stuff, just to see what it does there.
