You could also try in a hidden underneath spot while you have it off a melt stick for repairing the base on snow skis. Cheap and available at most ski shops. You light the end on fire then hold it close so the heat melts the surface as plastic drips from the stick to fill the gap. Make sure to clean it really well with starting fluid. Of course make sure the cleaner is well evaporated before beginning. It the re-texturing that will be tough. They do work but it takes a little practice. Plastic welders are available from Eastwood.com
