Had opti-coat applied to my new Audi at Orinda Auto Detail shop. The manager, Joe, is a very knowledgeable and professional young man. Joe explained all about opti-coat without any sales pressure a few days before I decided to have the product applied. I told Joe I'd like to see how he applied the opti-coat, and he called me just as he was beginning the application. I watched and asked questions, and Joe had all the answers. While at the shop, I watched Joe's team wash and detail some high end autos, and was very impressed. As long as Joe is running the show, this is the place to go for opti-coat and detailing.
