Most PPF mirror installs use either slip or gel. This can make finishing the edges a challenge and time consuming. Justin shows that by prepping the surface with Triple S or by polishing it, only a tack solution is needed for the install. As you will see, this speeds up every step of the install process without sacrificing quality. We feel that if you switch to this style of wrapping mirrors with PPF it will reduce the install time by 20-30%.
