I have a friend who runs a side business detailing cars and has about 20 Teslas that he details regularly. He has indicated to me that paint on Tesla cars is not very good as he's had to do paint correction on some that are only a couple of years old. With most of my cars I will put a clear-bra product like M3 or XPEL on at least the front hood lip to reduce the impact of rock chips which are notoriously bad on Colorado roads where sand and gravel is used in the wintertime to make roads passable. I've seen reports from some that they will put a clear protective wrap on much larger portions of the car, with a few indicating they will wrap the entire car for paint protection. What percentage roughly of the car are you considering? Let's say that hood lip is 10%, hood lip + side mirrors plus front bumper is 20% and so on.
