So I have been having some troubles with the lower weather stripping on my F150. Seems to be wearing through the paint on my doors! This isn't the epdm gasket itself but its like a rubber lip or flap. I assume to keep water and wind out of the door jamb. I've repainted them about yearly, and last year really did it right with a little sanding and multiple IPA wipes followed by acetone then primed and topped with touch up paint. Lasted better than before, but still wears through to the metal which results in rust formation (just surface rust, I keep on top of it). No issues with paint flaking/peeling, its pretty clearly a wear problem.
So this year, of course I'm repeating the process. But is there anything I can do besides painting yearly? Doors seem well aligned with tight hinges and latches. I try to keep the seal as clean as possible and well treated with silicone dressing. Would switching to a wax or even one of those special epdm dressings like gummi pflege or 303 help? What about removing the seal?
