Until recently I hadn’t look closely at my doors, but I found them to be terminally rusted on the bottom frame channel. I decided to pull the aluminum skin off the doors and (buying channel from RN) weld in new bottom channels and them either galvanize or coat the metal frame with rust converter.
Taking off the skin requires drilling out rivets around the handle area (round head solid rivets) and along the top (under the door top) pop rivets, where the galvy capping is attached. The edges of the skins are then pulled but to a straight position. Use a putty knife to loosed the putty that is between the metal and aluminum. The skin will then push off.
Taking off the door tops should be a simple unbolting of 2 studs, but typically water from the window channels get in there and rust them up. I had to soak mine for 2 days in a combination of power steering fluid and acetone, then do a lot of heavy hammering. The hammering damaged the threads but the bolts are totally rusted beyond use when I finally got the top off.
There is a way to either unthread the studs (if you can) or drill them out and put in new bolts. I’m not sure if I will replace the door tops or repair them. If I keep them they will require new window channels and studs.
