I would guess for angle eyes. I put mine in some loom.

Butyl tape came in from Amazon today, not quite $11.00 with tax, prime shipping. I re-sealed the vapor barriers on both passenger side doors, removed both drivers side door cards to check them out and both were still well stuck at the bottom, the drivers front had a bit at the top not sticking so I added some to it. In the process I broke some clips and surprisingly there were a couple of screws missing. So now I need to replace those that were broken and/or missing and I can call this issue fixed. For the minimal time, effort and money, I should have done this when the issue appeared a year or more ago. Luckily the car only spends, at most, 4 days per 4 week repeating schedule outside.
