I guess it's a mixed bag - and you need to use just a mist-ful!

The Amazon reviews are hilarious:

"Fry up a pan of delicious bacon, then soak a rag in the bacon grease. Use the bacon fat soaked rag to wipe the interior of your windshield. You'll get the same result and visibility with the added benefit of a bacon scented car."

"When the instructions say "Apply small amount" they really mean it. And it is supposed to prevent windows from fogging, but once they do fog up it becomes a total nightmare. It becomes a coating of wax on the windows, and wiping it off is very difficult especially if you are driving. And no amount of defrosting will help once it turns into this wax coating.

I'm going to experiment with very small amounts of this product, and probably not ever again on the inside of the windshield. Rain-X is an incredible product, but this stuff is the spawn of the devil and should be recalled before many people die."

Hmmm
