Thanks for the warning. I installed the moleskin anyway. It's working nicely. I'll cross that bridge when I get there!A word of caution on moleskin. As a Scoutleader I use this stuff frequently on hikes and the adhesive is very strong. Recall the issues and recall of skins by dbrand due to adhesive damage. Obviously the chemical properties of the particular adhesive used make a difference. It may be very difficult to remove from the narrow confines of that slot.
