So I'm getting my car painted soon and instead of having the shop do the body work on the rusted hatchback I replaced it. The replacement had the glass with the defrost and my original did not so I wanted to keep my original. When I took my original off it was just the small u-channel gasket and a ton of glue. The replacement I took off was factory installed and never replaced and it had an additional piece of glue/weather stripping that I can't find, even on parts diagrams. It was more like glue than weather stripping and it had a single piece of thread all the way through it. I wish I took a picture of it but I didn't. Does anyone have any clue what I'm talking about? I'm not even sure I have a clue what I'm talking about.
