I have read perspectives that Opticoat Pro is a great way to minimize ongoing detailing needs for the Model S, and provides some additional paint protection. Has anyone had Opticoat Pro installed on their Model S that would weigh in on their impressions? Did you have the interior done --what does that entail? Before & After Detailing in Raleigh, NC is a shop I found locally with experience on Tesla's (they have done three). Anyone work with Clay Dawson or this company?
