i removed my mouldings on my 2000 silverado and now theres this hair sized glue line all around the outer portion of where the glue tape was. i cant get the damn thing off for the life of me. ive tried scraping it with my fingernail, 3M adhesive remover and another brand as well. all im getting it a "squeaky clean" sound when i rub the stuff on. what else can be done...besides sanding and waxing?
