RRG is not a good lubricant and should NOT be used on sliding pins, it can be used on the piston seals that is it.
Some say use brake fluid on the seals, my experience of this has never been good as the fluid absorbs water and turns into a white powder which causes the seals to stick to the pistons.
After spending an hour looking about the grease that should be used for the pins is this-

After reading up I have changed my mind about using silicone on the sliders!, a tube of the above grease will shortly be in my tool box. |
that is antifreeze mixed with soap
RRG is veg oil mixed with fumed silica (both are lubricants in their own right) with a melting point of 250-350c. as i have said its not good for high speed bearings but is good for sliding pins. i seem to remember that the veg oil is good old olive oil... Castrol R springs to mind
dont waste your money or have the hassle with different greases when one will do.
