I used this on the front bumper cover of my '95 BMW 540i to repair some pretty bad damage from a raccoon impact at around 35-40mph. I've watched some 3M repair videos and used 3M adhesion promoter in preparation for sanding, drilling holes for gluing, etc. This material exceeded my expectations. Plan your work and purchase a nozzle kit as this material dries quickly. Repair areas support projector fog lights, so they must be strong. In the end I ended up with the ColorRite paint system in Alpine White III. I can't say anything ever happened.
