Its an epoxy resin with molydenenum disulfide (I doubt thats even close
on spelling!) mixed in.
They use it to repair the sliding ways of HUGE machine tools- the video
we saw showed a grinder with a table big enough to park a pickup truck
on having its sliding ways resurfaced with Moglice.

See http://www.moglice.com

He showed us a lead screw for a jig borer that had been recast in
moglice, and it was as smooth as silk, zero backlash. They also repair
ball screws by injecting them with moglice. He had one that was so
friction free it would run down the screw when held vertical, just like
a ball screw.

He did caution about using the proper release agent, else you glue the
screw into the nut. He showed on example of an acme screw about 1" dia
that they had to press out, it took something like 14,000 pounds
pressure to break it.

A 100 gram kit, which makes about 2 cu in of resin is about US$40.
Larger sizes are available.

He stressed that the epoxy was made to have very low shrink on cure. I
am thinking about an experiement with some WEST epoxy and graphite power
I have left over from a boat building job. WEST does suggest that
mixture for rudder bearing replacement in sailboats. Since Ive got a
bucket of the stuff on the shelf it will cost nothing to test. I have
some 1/2" acme threaded rod that is supposed to be good to about .003"
per foot I want to make a screw for the Grizzley with this combination.
