One of my personal clients had me do a three stage paint correction & wax on this 2010 BMW 550I... This car is a beast. Turned out amazing. His main concern was the water etching on the hood...Sort of visible in one of the pictures. Needless to say it all came out and the client was VERY happy Only crappy thing was the temperature in Toronto where I did the car was well over 100 degrees with humidity... Drank 6 bottles of water... Never pee'd... yeahhh... disturbing right?? Only used 3M's three stage professional Perfect It! system. Comes out mint every time with a Makita rotary polisher. Wax used was zymol.
