Myself, I would call them trim strips or something.
Do they really "seal" anything?
In the boating world, they're called "rub rails", and do serve a purpose. My KZ lost the RR one completely when it got hot the first summer we had the rig. Just slid right down the track and onto the ground. Idiots at the factory didn't bother to secure the top. Dealer replaced it with a non-matching piece, but it doesn't slip out. I have the same issue, in the same place as the OP. Just need to buy a roll of it and DIY my own fix. Just one more example of a mfr cheaping out on stuff that a $5 difference would likely fix.
