poorboy, challengersteve has been kind enough to give me a lot of info and like you say, no-go on skipping the gasket. I'm going to use the 3M products he suggested, and hopefully get the glass company guys (I need their assistance) to take their time the second time around, and get it right the 2nd time around. As I did the first time, I'll have the glass out and the channel clean and ready for the install. Even though this is warranty work this time, they won't have to spend time removing the glass and cleaning the old urethane out. I've already done this part, and it was no fun.
