[A/S] Drivers side window

["David" <david_ridings@xxxxxxxxxxxxx>]

Motorhome question:  The large drivers side window on my 1999 Airstream 
Cutter has the black snake like divider (for lack of better 
description) material creeping up from the bottom and is wavey, 
up/down. Anyone had experience with this and any suggested fix short of 
replacing the entire window.  I can just imagine what a replacement 
window from Airstream will cost.  Thanks, David
