I use Prolink at the moment for a SRAM 10sp setup. Seems to work quite well.
Bought the spray bottle size from Cell Bikes on special last year. Do notice that after a while chain gets very fine black gunk on it which can be wiped off with a rag and Prolink reapplied.
Tend to run kero in a chain cleaner and cycle the chain through for a thorough clean, and repeat until kero and chain is clean(er) looking and then reapply Prolink.
Waiting on some KMC links so I can remove chain to soak in kero when needed.
