I just heard about this stuff, has anyone tried it?

 

If you're talking about RAIN - X, Dry Magic, Spot Free car wash; looks kind of gold coloured in the clear bottle......I've been using it for quite awhile. I know it says "NEW!" on the bottle.
Works OK for the price and I always dribble water out of the hose over the car for the final rinse which helps slide away a lot of the standing water even with my polished paint surface.
However, "spot free"? Not a chance with the hard water in my city.

I've been corresponding with the Mr. Clean Auto Dry Wash guys trying to find out its advertised performance is affected negatively by using it on a polished surface. Answers that I've received are that certain waxes or polishes that are silicone based do not work well with the Mr. Clean product. Specifically Zaino.
They also claim that it isn't just the filtered final rinse that makes their product spot free without drying...it's the whole package.
Marketing or fact...I don't know.

I was hoping to see a few more comments on this board about members experiences with the Mr. Clean system before i try it on my car. I still am concerned about possible wax stripping, greasy film residue, spotting after drying, etc.
