I`ve been looking at Titans website about gg3/4 and there is a section-" comments on squeegee drag". It recommends keeping your rubber wet,squeegeeing JUST above the line of water and as few passes/strokes as possible. I think this proves there`s hardly any glide with glass gleam and why I struggled more with smaller windows(eg. opening lights) as my smaller squeegee couldn`t twist and turn. If, unlike me, you`re still prepared to use it or finish the bottle, you maybe better straight-pulling as you squeegee off- just straight strokes from one edge of window to the other. Gerry.
