Full transparency, I am by no means an expert on this; my testing and experimentation is limited.
I've been using this stuff on and off for over a year now and if used correctly, it's easily the most impressive lube I'm aware of, extremely smooth and more transparent than oil. The catch is that it can be an insane amount of work to get a switch to a happy place. For me, I've been diluting with distilled water 1:1, brushing on stem & housing points of contact (sometimes even the leaf), then allowing to dry completely (which can range from 1-5 days depending on weather conditions), then repeat. One coating usually makes very little difference, sometimes you can't notice any change at all. On average, I find you need to apply no less than 3 coats to make this stuff worth while. After 3 coats, it starts to shine. The most coats I've done so far is with a Gateron Clear, 6 coats… smoother than a Tealios lubed w/Krytox 106 at that point, no question. Obviously the spring weights are drastically different in this comparison, but the point is that the switch transformed from a "meh" switch into something impressive.
I usually lube spring ends with either oil or grease… RO-59 doesn't do too much in that area, at least in my testing.
So, my impression as of right now is that some people in the community are aware of how badass this stuff is, but it's also not surprising that it hasn't caught on. I recently put in somewhere between 25-30 hours actively lubing switches for a 108-key board… but the total process time took months because of all the waiting for drying, plus you need to keep track of how many coats each piece has, sheltering from dust over that kind of timeline, etc… it's not your typical lubing situation. This is an above-and-beyond kind of investment to do it right and it can take a toll on your enthusiasm for the hobby… unless you LOVE lubing like nothing else.
Maybe someone else has a quicker way of using this substance effectively? But like I said, it's unlike any other lube I've used, it's on another level… to me, it's kinda worth the insanity.
