I bought a bottle. Wasn't impressed. I've read horror stories and others swear buy it. It is not 100% aluminimum safe either. I still have the bottle and can't find a use for it. Thinking of selling it at a tag sale.
The one S100 product I liked was the motor black stuff. But you get over spray on everything. So after I spray my motor I have to go clean everything off.
Use WD40 its just as good, doesn't leave any white residue, years ago I justed brushed engine oil onto the black parts of the engine wiped off the surplus, it kept the engine black for months.
I've found it works quite well. You DO have to rinse it off thoroughly and it will leave a whitish tarnish on aluminum which polishes right off with a good metal polish.
It doesn't replace the quality of good ol elbow grease and paste wax but I find that if I wash & wax my bike thoroughly in the fall before storage and again (the hard way) once in the spring, using S100 through the season keeps the bike quite presentable with minimal effort. Fifteen minutes before I ride, I can spritz on the S100, hose it off well and dispatch the bugs and soil from the previous day's ride. I wipe the windshield with a paper towel then blow dry the bike at about 50 mph on the highway. That said, I've used other "waterless" products that are almost as easy to use as S100 and they work too.
