+1 with Astro4x4.
I had my tank wrapped earlier in the summer by a local guy here in the Peoria, IL area. I'm happy I did. Looks great. Most people don't realize it's been wrapped. These are the guys that did my tank.
I might even have the saddlebags done next summer. Keeps the chain lube, road rocks, bugs and my boots from scuffing the paint. I gave the guy $100 bucks. That was labor and the 3M film material. It took him an hour and half. He never had wrapped a Triumph tank before. I pulled the tank-bag power ring and seat off the bike. He had to figure how he was going to deal with the shape of the Sprint GT tank. He used three separate pieces of material to cover the tank.
He was quite knowledgeable about the film. The 3M material does not block UV light. This allows the exposed paint and the paint under the film to fade equally. He said, " Factory paint is not harmed by the application and removal of the film." He also said, "there was no warranty against a "repainted surface paint damage" when it comes to removing the film. This is due to the fact that paint adhesion varies greatly to the base material due to less than perfect paint techniques. He did follow up that he has removed film from many repainted surfaces with no damage. He said he uses some low heat and a lot of time and patience.
He used a very sharp razor knife, a hand blow-dryer and a spray bottled,filled with distilled water, alcohol and (I think) a literal "drop" of soap, to act as a lubricant/surfactant when he did my tank. It was fun to watch him work his magic.
He told me he wrapped a very expensive bi-turbo Porsche, that's in the Peoria area, with 100% film coverage. He does a lot of film wrapping for new car dealers selling the higher end auto's.
