Black Gunk on the Clear Plastic Behind Behind the Door Panel
 

What is the stuff? I need to replenish the supply in a couple spots because the plastic keeps falling off. The door panel will be back on soon enough, but I'd still like to get some more on there.

It is like caulk strip. 3M makes some similar stuff. I used to be able to find it at home depot. Comes in a rectangular box (10" by 5" or so)

go to a glass shop it is called a soft kit made by 3m a roll is about 20 bucks
