[W126 Coupe] window motor/regulator

[Dick Spellman]

Hi Alex:

If you have any spray adhesive,  just put a small width of it over the 
previous adhesive and you should be good to go.  As for the rust on the 
doors, you may have bad outer window seals ($15 US or so ea. at MB 
dealer) that are easily replaced that will prevent the doors rusting 
from the inside out.
