As many of you probably know, the RoboRaptor's inner foot pads, (as shown here)
grind down very easily, even on linoleum. I've come up with a solution to help make the pads more slippery (which is desirable) and it will help protect them from grinding down. Perhaps some of you have already thought of this. The solution is 2 to 3 coatings of........ fingernail polish. It's been working for me. Just thought I'd share my experiences with the community. See ya!
