RT Jam:
Thank you for posting your efforts to resolve this problem. I hope to speak with some friends who do their own bodywork and see if they have any suggestions without making the problem worse.
I keep replacing trim screws as they rust but I realize that the screws are just an indication of what's going on in the door.
I was hoping to keep this PA for a long time since it only has 74k miles and I drive it about 3k miles a year.
Thanks again for posting.
