I'm not even going to bother giving a star to this one.
Crystal Fusion is this fancy stuff they convince you to buy when you buy a car at a dealership. They dazzle you with this little jar of "muddy water" that has half of it painted with Crystal Fusion on the inside and half not. So when you mix up the jar, you can see where the mud sticks and where it doesn't.
Then they dazzle you about how it protects your windshield from all sorts of things--not just precipitation! But from bugs sticking and from rocks chipping. That's right, your windshield won't chip nearly as easy with this stuff! And there's warranty too! If you get chipped, they'll replace your windshield for you!
