Is there an actual part number for the U-shaped rubber channel that the glass sits in for a late style window?

PET doesn't show one. I might try a local auto glass place here but I typically run into the small town blues when doing so.

Any good alternatives.

Thanks in advance!

Electrical tape or the pipe wrap for gas piping works

There is also metal glazing silicone available online but it comes in a gun cartridge.

Thanks!

I have Windo-Weld Urethane but that seems so "permanent".

It would probably require breaking the glass if removal was needed?
