I'm very interested in this too. I just bought a used e92 M3 in November and was planning on getting the front end painted, bumper, hood and fenders this Spring. There's the normal amount of highway chips for a 5-6yr old car, but I'm pretty anal about this. I was looking at getting the entire front end done so there's no seam or visible line where the PPF ends. I was quoted $1300 by ReStyleIt from the car show (it was a special...) so its definitely not cheap, comparable to a front end re-paint, but just saves you the hassle and time. This is for the best film they had, the new 3M ScotchGuard Pro (7yr warranty) - I wonder how does this compare to the XPel Ultimate (10yr warranty) in real life.
The results of the first and second videos seemed quite opposite...
