The SanaGlos optional finish on Totos is super smooth, and has some anti-microbial properties. A wax would make things smoother. Not sure what the life of it would be, but I don't think it would hurt. If I was going to try this, I think I'd try one of the high-tech nanowax products. A bit more fiber in a diet pretty much eliminates the skid marks, though, and is good for that and can help lower chloresterol, too.
