S100 Engine Brightener for Motorcycle Engine Cases, black plastic cleaner and more

I have to admit that I was prepared to be under-whelmed by this product.  I'm not sure why; maybe it's the packaging that didn't do it for me, or maybe it's that I couldn't quite figure out what it was really for.  An "engine brightener"? 

What was that supposed to mean?  It claims on the label to be good for paint, plastics, and rubber, then it talks about "grayed out" engine casings.

So I left this test for last.  I have plenty of black engine casings that were getting pretty "grayed out", so I tried a spritz or two on an unobtrusive spot. 

I have to tell you I was really amazed at how S100 works!  It really did turn a "grayed out" black painted engine part into something that looks brand new! 

I went back and read the label again and it claims to be a "technological breakthrough" that can "take the heat" and bring the factory black look back to life.  I believe it! 

It's kind of a weird product -- you spray it on, it leaves a kind of film that almost dries; then after a minute or so you wipe off the remainder.  It actually does feel like it "lubricates" the painted surface of the metal!

My skepticism caused me to hastily apply the product, but I now feel that it will work even better if you first clean the parts you're going to use it on.  I'm going to try it on everything around my engine now that I know how good it works.  Definitely recommended! 

Here's a shot of the lower front section of an engine, right behind the front wheel.  This area takes a beating from mud, road grime and stone chips.  I didn't bother cleaning before I tried applying the S100.	Here's the same area after a couple of shots of S100 Engine Brightener.  Your eyes aren't deceiving you -- the parts actually look brand new.  The few remaing spots are bugs; I'm sure if I would have cleaned it first that this area would look even better than it does.
Here's a shot of a right front fork before treatment with S100 Engine Brightener.  These black painted forks take quite a beating and are probably the most "grayed out" parts on the bike.	Here's the same fork after the S100 treatment.  It doesn't take away the chips and dings, but you can see how it makes the paint look fresh.  I'll report back after some miles to see how well it stood up to the rigors of the road.
