I’ve heard of people using Super Lube for switches, definitely not something I would do either. Hell I even won’t use SL for stabs anymore TBH. Although I think there may be a few very specific SL greases & oils that are close enough approximations to the oft used Krytox greases/oils by the KB community. The problem as I understand it though, is SL makes a metric shit ton of different greases/oils with a much wider range of viscosities than Krytox. With a very confusing numbering/labeling scheme to boot.
Understandable to try for people who live in areas where Krytox is very hard to get/expensive to get shipped to, but a pretty poor choice for anyone who easily acquire Krytox or Tribosys. OP I would do some more research into what SL greases is comparable to Krytox 205g0 & use that just by itself with a ultra thin application if you’re stuck with SL. Otherwise just get some Krytox 205g0, Tribosys 3204 or Tribosys 3203 IMHO.
