It is highly unlikely for paint protection film to harm OEM paint. Paint systems used on modern assembly lines today produce a minimum bond strength of 16 MPa and maximum of 25 MPa between the panel and the paint depending on color, iridescence and the system used. Our film’s bond to the painted surface at normal state (immediately following installation) is .0753 MPa. Even after years of heat and sun, the bond between the film and the paint increases to only 0.17 MPa. What that means is in the absolute worst case scenario, the bond of factory paint to the panel is over 94 times stronger than the bond of our film to the paint. In the best case, the paint is 332 times stronger.
That being said, it is still recommended to have a professional remove the film in accordance with our published guidelines.
