i replaced the rubber gasket on my windshield a few months ago. did the "sun" warming technique and not unlike fireout1, the corners did not set in very well. first rain storm i knew exactly how well it worked...just about as good as the old weather checked and cracked original window seal. many hours later and some interesting sealing operations i think i've got it weather tight. some rough spots where i had to fill some gaps but i'd rather have a good seal even if it doesn't look perfect.
