I have been using this stuff for years and I love it!
Wurth High Build UnderBody UnderSeal

Wurth Aerosol High-Build Underseal is a fast drying rubberized spray undercoating ideal for resurfacing wheel wells and lower rocker panels. UnderBody spray provides a permanent, flexible black finish that will protect against road debris such as rocks, rust, water and road salts. It is ideal for touch-up and offers easy cleanup.

I rest my case.

I have used this stuff on some pretty extreme parts, and it has stood the test of time.
