I have a 2005 3i and have a question with the front bumper. The lowest section of the bumper comes to a vertical lip. I assume it is for aerodynamic effect. It often drags or pulls when leaving the concrete wheel stop in a parking lot. I try to avoid getting too close to these but nonetheless have caused a small zig zag crack at this vertical section. What would be the best adhesive to use after gluing and realigning this small area? Thinking about using Gorilla Glue before paint touch up. Any advice would be appreciated. John Fogarty
