Jim has suggested duct tape and the adv med .9 ultralight that ras has suggested has duct tape as well.
I've used it in past to keep a burns from rubbing and breaking blisters or at times small wound to stop bleeding.
Is that the entended use for duct tape or per red green, duct tape can fix anything??

BTW, jim is your kit @ My updated FAK commercial kit or something you added to from a basic kit?
