Michael had brought me his E46 M3 for a full detail a few months ago and he recently picked up a new Audi S6 and boy is it gorgeous: Daytona Grey Pearl with red leather interior. He wanted to give his car the best protection since he plans on keeping it for years to come. So Opti-Coat Pro+ was the obvious way to go with 7 years of protection. We will be doing the wheels and brake calipers at a later date as well to keep the brake dust from the massive pads from bonding as easily. Thank you again Michael!
