Just a heads up for those using wooden and steel screws in vises, etc. I do not know how it would fare in machines, such as a tablesaw.
I’ve been using Selley’s Ezy Glide for a while now. The active ingredient is PTFE (Teflon). It seems to do a good job of smoothing the passing of a screw. So far I used it on wooden screws in a leg vise and Moxon vise, and the steel screw of the end vise. It dries clear and does not get greasy or attract sawdust.
