Making Soap and Seal

This is a very simple product to make.  To begin I measure out the water by putting 95 tablespoons in a bowl.  Then I put four tablespoons of the silane.  This is the brown bottle with the blue strip in the video.  Next I add a single tablespoon of Dawn.  I am supposing you could add any window cleaning soap/product.  Then I put the mix in a 16 ounce plastic bottle using a funnel.  So it is essentially 95% water, 4% silane, and 1% Dawn.  Very simple.

To apply just wet a dry applicator with Soap and Seal.  Apply to a dry window.  Then squeegee it off.  It is possible to rinse it off too using a water fed pole.  The new surface you create will be hydrophobic.  But not as hydrophobic as Rain X or Aquapel.  It is actually possible to coat treated glass with pure water.  I used the window of my car to show this in the video.  I sprayed the windshield with a garden hose using the soaker setting.  After applying Soap and Seal to a circular area on the windshield.  The water covered every square inch of the glass.  But.  When I broke the surface tension of the water that covered the area I had treated with Soap and Seal using my finger;...the water instantly broke away sheeting out to the edge of the circle.  

I don't like the terms hydrophylic and hydrophobic.  Rather I use the scientific term contact angle. Superhydrophobic is around a 150 degree CA.  Superhydrophylic is down to a 30 degree CA.  If my memory holds.  What WFP guys want is a sealant that is actually right in the middle.  Not one or the other.  So that the rinse water will easily cover the glass but then "sheet off" instead of forming hundreds of very small beads/drops.  This would help in preventing the deposit of silica water spots. Since we get spots from drops.
