While I was in Calgary recently, I had OptiCoat Pro applied to my P85+. It was handled with due care and professionalism by Carlos Baca of DetailingBliss. The process took 2 days as the car was done from top to bottom. OptiCoat was even applied to the wheels and glass (with OptiGlass) but the price was still quite decent. I highly recommend him if you are considering OptiCoat Pro or CQuartz Finest application for your Tesla. A detailed writeup of the process (with photos) can be found here.
