What lubricant to use on tow dolly swivel pads
I removed the swivel platform on my tow dolly by removing the center bolt. There are two pads one on each side that are 10"x18" by about 3x8" thick. The pads are made of some kind of composite material that is not very slippery ( unlike a 5th wheel pad under the hitch pin ). So my question is what should I use to make the pads "slick" so that the swivel platform that the front wheels of the car sits on easier to move. I am concerned that if I use grease road sand etc will stick to it and cause problems. I am thinking more along the lines of a dry lubricant but I'm not sure which one. Your thoughts and suggestions.
