This space age coating makes small bumps in the road seem to disappear. MOS2X is a surface engineering tribological coating used on Aircraft aluminum in specialized racing vehicles to reduce friction and insure long life. Also includes fender and brake mounts. *Street or track, nothing beats MOS2X.
