I've done that. The salted nail polish chipped off and took the markings on the ruler with it.
I haven't tried this but think it would work well. Just put a tiny dab of clear silicone on corners of underside of ruler. Smooth so it is almost flat and won't raise ruler up much but I bet it will keep it from sliding. If you ever want it off, I think it is fairly easy to rub off.
