These tools are used for sealing the vinyl edges of perforated vinyl, vinyl that is really stretched during an install, or spots where the vinyl will be exposed to moisture and chemicals (such as under the bumpers and wheel wells). For window perforation, you have the option of using liquid sealant or lamination tape. Liquid edge sealant dries fast and each pen will seal approximately 10 sets of truck doors. For bumpers, edge seal tape works best. For wheel wells, liquid edge sealant is recommended.
