Did you decide on who would do your car?
I just took possession of my model S. After reading this thread an others I decided to go with RJ at Raja Speed & Tech Motoring at 1 (703) 565-4508 in Aldie, VA not too far from Dulles. I dropped off the car today.
Every company/tech took their time to walk us through the process and their experience is vast. But in end RJ had the best price, years of experience, referrals/testimonies and pictures of his work that made us comfortable. After speaking with so many shops I had a lot of questions about the process, to wrap or not to wrap, which tint was better and would not turn yellow, which top coat would you apply on the satin film, do you apply opticoat on the interior back seats and the door sills and entry to prevent/minimize scuffs, etc., and he took his time to answer every question without bias and when it came to the tints, he explained the benefits and differences between Suntek, Huper Optik, Xpel and several others. In the end, my wife said he didn't try to convince to go with him but rather educate us and make sure we knew what we wanted plus his prices are very fair and competitive.
We went with the full wrap in Xpel Satin on my silver Model S. For the tint, I went with Xpel Prime XR.
I think the key for getting the wife on-board is to make sure she's involved early and often, but I still got the look and heard "no more".
The key is research and go with the company/tech you feel comfortable with. For us, RJ did everything we wanted, within reason, and within our budget. If you decide to use him, mention Mitch with the Silver Tesla.
