Here at Armored Clear Bra PPF, we don't recommend trying to patch Paint protection film, or clear bra. There are several reasons we don't attempt patches. The first reason is that you NEVER want to cut into your Vehicle Paint (Armored Clear Bra PPF always precuts our clear bras prior to installation, using a template). The second reason is that any patch would still have visible edges and would never look quite right. That's why we always remove and replace the damaged section. For example, if a Bumper clear bra had some damage, we'd remove it from the Bumper, cut a new Paint protection film to match, and reapply it to the Bumper. Good to go with new Paint protection film! If you have any issues with your existing Paint protection film, call Armored Clear Bra PPF at (801) 896 9538 for a free estimate on replacing it!
