I am thinking that removing the plexiglass from the door and the left side window is going to be required to properly prep and paint the frames. The rubber seal around the window is showing its age. Has anyone replaced theirs? I didn't see an obvious item on univair's website. I need to go find my parts manual and see if it is listed there. Looks like a case of drilling out rivets in the aluminum frame to remove the plexi and then I'll be free to sand, prime, paint those.
