Pam is an oil-based cooking spray used to keep things from sticking to the pan. It does work to dry nail polish faster in a sense. The oils float on top of the surface of the nails and keep things from actually damaging the nail polish. however, It is oil, so it can be hard to get it off your hands while leaving it on the nails. And you can't really add another layer of polish until after the oil is completely removed, otherwise it slips and slides around instead of sticking.
