Replacing Side Windows - 1923 4 Cylinder

[Guest 1923 Buick 23 Series Sedan]

I am replacing all the windows in my 1923 Buick.  The windshield was "easy" but I am struggling with the side windows.  I am lubricating the compression rubber strips but when I press in the glass its destroys the rubber.  I have used WD40 and then soapy water but still have issues with the rubber getting wrecked.  Any suggestions?

You might try silicone spray.  It is sometimes recommended to restore dried out rubber seals. 

 

You can get it a craft stores as it is often used as a parting agent for candle making.

 

Just don't use it if you will be painting the car.  Paint shops will not let it in the door because it makes surfaces virtually un-paintable.

Before silicone spray, try "Ru-Glyde," a rubber lubricant used by tire shops for tire installation.  It's a milky liquid and not a problem for future painting.  I'm pretty sure that NAPA can get it for you if it's not on the shelf.  But you may have to buy a gallon....

Try good old fashioned Lestoil cleaner.  This is great stuff for rejuvenating dried out rubber especially tires.  I use it straight out of the bottle.

Make sure you have the right thickness of the rubber setting tape.  It comes in at least three thicknesses.
