I am replacing the bottom Windshield seal that goes between the windshield frame and the car body (cowling). The old one came off pretty easy, but I need some "guidance" on how to install the new one. My aluminum channel is in very good condition. Do I heat the new one up first? Use some sort of "lube"? Unscrew the bottom windshield frame first and then slide it in? As always, thanks for your help.....AL
