Be careful not to spray it on things that it shouldn't be sprayed on. Not only will it slick-up the rollers as you would expect causing loss of traction, but more, some of the sprays have components that will melt into rubber wheels and parts. So be careful to use a sheet of paper or otherwise mask off all wheels and rubber stops, pads, and grips that you don't want to lose their grip and/or be softened or melted by the generic sprays.
