Best thing I could have ever done. If you are doing it yourself, give yourself enough time. I scuffed and cleaned the interior maybe three times. And my gf and I spent 2 or 3 hours taping stuff up since I did not take everything out of the vehicle. O yeah, and taking out the seats will be a hassle. I went to an sts shop and gave the guy 10 bucks to remove the bolts for me because I dont have access to air tools. There are a lot of articles and write ups on here and other forums.
I am building a customers 99 right now. Entire exterior and interior are sprayed in raptor liner. Looks great and has fantatic durability. Its a monster of a build that includes changing his tan interior to all black. Should be done in about two weeks and I will post up some pics
