SEM make a great product for repairing plastic called "Problem Plastic Repair". Its a 2 part system and is enhanced with the addition of mesh tape. I used it on my 4 wheeler rear fender. I've hit, bumped, flipped, and slammed that fender and the repair has not let go. You imbed the mesh tape into the wet repair filler. Once it sets-up, its ready to sand and paint.
