Two recommendations... first is the Orinda Auto Detail guys. They do XPEL film and showed me some of their work in progress on Tesla's in their shop. I didn't have the film put on but had them detail and put Opti Coat Pro on my M5. It looks amazing! Based on how great their work was on the detail and attention to detail on my car, I would trust them to install XPEL film.
2nd recommendation is Juan at
http://www.transparentbra.com/. He installed my window tint... did an amazing job, so I would also trust his work for clear bra install (also got this recommendation from a fellow board member who recommended his tint + clear bar installs).
