Is there matching coating?
 

We pulled the gas tank. It is in decent shape. There is a little of the undercoating peeling around the sending unit and another small area. Is there an undercoating for sale that I can get close to matching the original? I'm not concerned about exact match I just want to protect the areas.

This has been discussed quite a bit here on the forums.
