Thanks for the insight, Luke...
This guy has a rope (it might be too big in diameter) that he is using in the channel but he is not using soap... He is using WD40! On top of that, both times he has started at the bottom... I don't think the rubber is getting seated down properly on the pinchweld area... As he works the glass in the best he can, when he finally gets up to the top, that's when it breaks!
Anyone else got any pointers?
