I used Captn tolley on joints around the windows, doors and around panoramic windows on the 2005 classic.
it appears when it dries it a clear strong material that looks to be inert for the most part. You should cut the tip real small..and clean the area you are you are going to reseal.
I just let it dribble while moving it along the cracked gaps stopping when i was really taking the juice. I flows nice around the curved frame of the glass sucking in along the way.
I plan to retreat the area again, after this heat breaks in NC, to make sure it a good seal.
highly recommend and keep a good supply of paper towels on hand to catch over fill..
