I think they're called "rails" anyway... Not sure of the true technical name. They are the part of the body that runs under the doors from one wheel-well to the other on the same side...

Anyway, mine are rusting out and bubbling up the paint from underneath. I really want to tackle fixing these and halting the rust here when the weather gets dry again. I've been toying with the idea of fixing them up with bondo and body work, then painting them with some kind of protective coating substance (truck-bed liner?) or covering them with some kind of protective film type stuff that would stick on. I'm musing aloud here. Perhaps I'm crazy.

Does anybody have some tips on fixing this problematic rust area? Where does the water work it's way in? I thought that my first cheapy paint-job would seal them up and stop the rust at least for a couple of years, but no such luck. One guy I bumped into suggested that I drill out a hole in each of them and inject a bunch of a substance called "Waxoil" to halt the rust. Any other ideas you fine folks out there have?
