Will 3M Adhesion Promoter Affect Car Paint?
2 Answers
3M adhesion promoter will not affect car paint. The components of the adhesion promoter do not cause chemical reactions with surfaces such as car paint, metal, glass, or plastic. The adhesion promoter is mainly used on automotive modification parts such as car sealing strips, rain guards, handles, mirror covers, window trim strips, scuff plates, and grille trim strips. For sealing strips, the adhesion promoter can provide functions such as shock absorption, sound insulation, waterproofing, and fixation, and is used in various parts of the car including doors, windows, and windshields. Although the sealing strips come with double-sided tape, the adhesion promoter can create a good bonding surface between the sealing strip and the car, significantly improving the adhesion effect of the sealing strip.
When applying vinyl wraps to my car, I've used 3M adhesion promoter with no observable damage to factory paint. Its main components are alcohol and acrylate, which evaporate extremely quickly - leaves zero residue after wiping the surface dry. Three crucial notes though: 1) Never apply on cracked/exposed primer areas as solvents may penetrate and worsen damage; 2) As warned by wrap installers, always wait 10 seconds after spraying before applying film - trapping moisture causes PPF corrosion; 3) Once encountered counterfeit products with unbearable fumes that stung eyes and caused white haze on paint. Now I only use authenticated products with anti-fake labels, followed by immediate double-wiping with dry cloth for peace of mind.
