Product description

Fast removal in one piece without any adhesive residues even after various oven cycles or pre-treatment of attachment parts.

Prevention of paint overspray to get on areas of the (USW) bonding area as this makes the bonding of parts in the car interior and exterior very challenging. USW-Welds or liquid glue require a clean and unpainted plastic surface to ensure a secure bonding.
