As previously stated the 3 m product carries a 5 year warranty. They also recommend it be removed after 5 years. I had 3 m on my wife's Mazda MX5, steel and plastic covered. The film developed holes after 4 years. I took it to a installer in North Tampa, I had the original receipt, he called 3 m. They covered the cost of the new film but not the removal. I paid $150 for removal, and he installed what he claimed was a better product, not 3m. I had no paint removed in the process. I realize this was not fiberglass and may be easier to work with. I have also been told by the installer that put the original 3 m on that not to put it on a vehicle that has been repainted or on paint that has not been baked on. I don't know if they bake the paint onto motor homes like car manufacturers do. This may be the reason the paint comes off when removing the film.
If anyone wants the dealer/installers name in Tampa, send me a pm and I will look it up for you.
