PPF misconceptions versus reality: MYTH "it is just thick clear coat" (no, urethane is entirely different material with impact absorption properties paint lacks). MYTH "rocks still chip paint through PPF" (no, film absorbs energy preventing paint damage, film itself might show impact but paint underneath is pristine). MYTH "it hides existing chips" (no, PPF only applies to perfect paint, installers will not cover damaged areas). Our PPF science guide explains the material properties: urethane elasticity allows 6-8 mil film to flex under impact (distributing force), paint is rigid and chips when force concentrates (why unprotected paint fails), self-healing polymers in top coat reform after minor scratches when heat applied, film is replaceable when damaged (paint is not). Article includes high-speed impact testing videos and cross-section analysis showing film vs paint damage resistance. Real protection backed by materials science.
