I could only find one supplier of the "Slip Plate" brand, and it was

Slip Plate is essentially a long wearing paint loaded with graphite.
The other is just graphite. Slip Plate won't create a mess like an
ordinary graphite lubricant, it stays where you paint it & provides
some corrosion protection as well as lubrication. With Slip Plate, you
may have to make some allowance for the thickness of the stuff.
