I totally love your thinking. Thanx for adding that link to this thread!
Let me first show you a picture of what Nanovations says is the difference.
Remember now that this is biased info. And Nanovations will tell you that they have a self assembling polymer that “treats” the glass on a nanoscopic level. Which if the picture is correct demonstrates this very well. Glass pores are about five microns across. Each micron equals a thousand nanometers. So their treatment could be around a hundred nanometers thick.
I am guessing because of these properties it is definitely not a PDMS which stands for polydimethyl siloxane. Very interesting your reference says that Rain X has sulfuric acid. This chemically reacts with glass. It is a glass etchant. And is the primary reason why Rain X “sticks” to the glass. If you just let it run down the windshield you can see the effects of this. I also know the application of Rain X is different too. When I apply the NG1010 I don’t get the “shmear effect”. But Rain X is notorious for this. Also Nanovations says that the NG1010 is rain ready in 30 minutes but that it takes 24 hours for the SAM (Self Assembling Monolayer) to form. Which is radically different from the properties of Rain X. For these reasons and more I don’t believe that the NG 1010 is anywhere close to the same chemistry. But I can’t tell you exactly what it is.
Nonetheless the bottom line here is we really don’t care what the chemistry is. We just want a product that is going to hang in there for at least six months to a year and help us get the hard water spots off way easier the second time around. Marc Tanner has already set up some experiments a couple weeks ago. The preliminary results are promising. I will keep everyone updated.
