Total noob at PPF stuff. I bought the double package figuring I'd screw up the first round. Maybe I did, maybe I didn't. I didn't give up on the first try and they seem to look fine. I'm not sure this gave me enough experience to try the hood black out thing but it does help build confidence. I used the additional cost fluid, towel and squeegee. Anyway this appears to be worth the money. Go for it!
