Greasing chocks?

[Dusty Yevsky]

Is this a good idea? I’ve heard or read somewhere that this should be done but I can’t remember where. If so, does one grease the entire inside surface of the chock where the runner rubs? Or just the bolt hole in the runner? What kind of grease? Would grease become a grit magnet and require constant renewal? All opinions are welcome

Only one of my runners has plastic shim-tape, so I use grease almost all the time.
I apply a thin layer everywhere the runner will contact the chock. The inside of my chocks are polished to about 1500 grit, so I'm very careful to avoid scratching them. I wipe it off and reapply every day (both from the runner and chock).

The best grease I've found is Startbrite PTEF Trailer Hitch Lubricant. Its viscosity remains constant well below 5F.

I also use the stuff for my (non-ball-bearing) mast socket.

Thanks Geoff, this is just the information I was looking for.
