OK, I realize that is not the scientific word for it... What is the vinyl strip that fits into the channel around the window where it is riveted (or screwed) to the sidewalls called? And where might one find it? The guy at the RV place showed me a RV Trim Repair Kit, and the trim it T shaped and about 1" wide... not what I need. This is about 1/2" wide and shaped like a flattened out U, and is squeezed into the channel.
When I removed the trim to take out the windows
, it was so brittle it cracked and broke. I'm guessing it was very pliable when it was new 32 years ago :) Thanks!
