go to any auto parts store and buy silicone spray .. not the type where you use to cock a bath tub .. it comes in a bottle like WD-40.. roll down the windows and spray the rubber, tracks, part where window is seated when its rolled up or whatever you wanna call it. i dont know the exact name right now.. roll the window up and down couple times and keep spraying until its good. this will lube up the tracks and silicone wont dry for awhile
