Top rubbing against trunk liner - depends on where you are talking about. If you are talking about along the side near the back when the top is folded, TS posted a mod a year or so ago that involves pinning the trunk liner back at those points. Makes the trunk close easier too. Is that where you mean?
I noticed that my top was fraying on the bottom side of the buttress where it folds. Since it is normally not visible, I have duct taped it while I think of what better to do.
