A few days ago I posted a question about removing the black plastic door sills. Now I'm glad I did.
I found the beginnings of rust on all (4) door sills [I have dual sliding doors], especially on the driver's door. As I suspected, the black plastic had worn through the paint, and the door sills trap moisture, leading to corrosion. This could be really bad in a wet climate.
I used a Dremel tool + wire brush attachment to clean up the lightly rusted areas. Then I put a couple of coats of Herculiner truck bed liner on the bottom of the sills, making sure I didn't block the drain holes. The Herculiner was about $30 at Kragen and one can was sufficient to do all (4) door sills.
I did the same thing with the plastic strip that runs under the rear doors as there was some light rust forming there as well.
