as I said i have done this on many cars, x3 911's, my 370, focus rs, x2 clio's, x2 bmw's etc etc the focus rs is running 414bhp and one of the 911's is a turbo so i knpw heat is not a problem
I think the finish is as good as any I have seen
I couldn't recommend it if I wasn't sure it worked without fault but hey ho
