I just had Marcus and crew do a lot of work on a Tesla Model S and Tesla Roadster. On the Model S they put on the Xpel clear bra, 3M Crystalline Tint, and and then OptiCoat with paint correction. On the Roadster, which had a lot swirl marks, they did the OptiCoat treatment with paint correction. The cars look fabulous! The Roadster, in particular, had a lot of swirl marks (bought the car used). It looks so much better now. The color also looks deeper and richer. The only drawback was that it took a little more time than originally estimated, but the quality of the work is outstanding. I highly recommend.
