Thanks for all the replies. I'll give the silicone spray a try. I don't want to go with a replacement window because I like the bright finish on the original.

I've driven this truck for a few weeks. While it needs some electrical TLC due to some "handyman work" (lots of Scotchlock connectors), it drives great. The power of that 402 with a big fat Edelbrock on it is amazing.
