I made one out of clear contact "paper", actually plastic, that I bought at a crafts store. I'd bought one of the black protectors from Nashbar a long time ago and never mounted it, and when it came time to use it, it had become hard and the glue dried out. To make one, I rough cut two pieces of the contact paper and stuck one atop the other, then traced the shape of the old Nashbar protector onto them. Once cut and mounted onto my bike's stay, my homemade protector is practically invisible and has done its job excellently with no separation or pealing.
