Hi,

I've got the same issue. On both front doors there are spots at the edge of the plastic with rust starting.

I havent fixed mine yet but I can tell you what I am planning on doing.

Remove the plastic panel. This can be done by removing the two screws visible when you open the door, then you need to undo the snaps on the lower edge of the door (I think there are 5 from memory). These are supposed to be a pull straight out snap - one part stays on the plastic one part stays on the metal. I was worried about the strength of the plastic trim. If you lie down an look at the lower edge of the door from below you will see the clips. You can unclip them individually from below (which is what I did). once the lower clips are free the panel slides about 1 inch rearward and then comes off.

With the plastic off you can get at the rust.

My plan is scrape off rust and wire bursh and sand. Then paint with POR-15 (I ordered their starter kit in silver on Friday). To insure the surface is flat I plan to fill it after painting with POR's straightline body filler. Then topcoat with white to match the car (I believe my paint code is 147). The person I talked to at POR said I didn't need their primer, so I didn't get it.

I believe there are local places that will get color matched paints into spray cans for you. I'll be checking one in the next few days. Or you can order from Tower Paint which gets mentioned on these lists frequently.
