Check out this video for awesome tips on how to repair cracked and broken street bike fairing with PlastiFix.
PlastiFix can also be used to replace missing tabs on motorcycle fairings.
Zip ties are nylon, most motorcycle fairings are ABS. They will not blend well at all. Also, baking soda and Super Glue (CA glue) make a very brittle joint, has low strength, poor shock resistance, and is very difficult to sand. PlastiFix is tough, high strength, and bonds GREAT with ABS.
