Chain Waxing

It sold out in minutes, but $25 I think.

It's basically a wax-based lubricant with a thinner alcohol carrier, and an additive:

Secret Chain lube also utilizes the world's fastest, most lubricious additive, nano-scale Tungsten Di-Sulfide. NanoPlatelet WS2 has less than 1/3 the dynamic coefficient of friction of PTFE and 1/4 that of Molybdenum Disulfide (MoS2.). Even better, the nanoscale WS2 seems to lock up in the crevices of the metal and stay there even after cleaning/melting off of the wax. In theory, the chain will get faster with age due to the WS2 loading up on these surfaces.”
