My zipper gave out on the bag for my S2. Scott Smith gave me a couple of suggestions to give it new life. First he said run it through the washing machine on a cold cycle and let it air dry. Take pliers and give the zipper slide a slight crimp on each side (careful…. just a slight crimp or it won’t work). Lastly, apply Sailkote lubricant to the entire zipper.
Well it worked pretty well and the zipper is zipping. Thanks Scott.
