I picked up my Model S from the factory in Fremont last week. At home, I noticed certain parts of the car (most notably the panel above the front left wheel) had a rough texture, sort of a gritty sandpaper-like feel. I chalked it up to caked on dirt from the car sitting outside at the factory. I then had the car detailed and Opti-Coat applied over the past weekend. The rough areas are smoother, but still some gritty feel in some patches. Is this correctable at this point or would I need to get the Opti-Coat removed to fix things?
