Brad's pretty much covered all the bases here 59'Chev.
If you can, install the rubber to the glass the night before and secure it with 2" masking tape.
Overnight it should take a 'set' to the glass,and make things a little easier.
Just a tip....I use plain old glass cleaner to lube the rubber,it dries off better and doesn't leave any residue....
Good luck!
Jock.
