I picked up some S100 at Royal Dist. this weekend and gave it a try. Wow, what an amazing product. I had been on a 1500 KM Pennsylvania trip the previous weekend and had lots of chain fling, road grime, and bugs covering the bike. I sprayed it on, gave it a bit of rubbing with a soft cloth on the front fairing to work the bugs a bit and hosed it off. I couldn't believe how bright the sprocket looks after the cleaning. I didn't rinse it off my driveway very well and it left some marks but I assume today's rain will take care of that. If not, I'm going to have to take it to the coin wash next time.
Got to give it a good rinse - a really good rinse. I'd avoid the hi-pressure spray though.
I used the stuff on the engine / engine bay of my pick up the other day. It's only 3 yrs old, but the dirt looked 100yrs old. Now, it looks brand new again.
