The rationale of the product doesn't make sense to me.  Supposedly it causes the cells to retain water.  I know a lot of northern growers have problems with winter desiccation, but Polymer Ag is applying that to short frosts.  I've never heard of desiccation occurring over a few hours..  My understanding is not that fruit gets damaged from desiccation, but because the water in the cells freezes, expands and ruptures the cell.  I can't see how retaining water in the cells would prevent rupture. 
 
Additionally, the product supposedly provides a "mini-greenhouse".  My question is, how could such a thin film provide any real insulation value.  In a real greenhouse,  the air acts as an insulator.
 
I don't want to be unnecessarily negative on the product, but I've used another product advertised as a frost protectant, and couldn't tell that it helped at all. 
 
That product also advertised the same type of evidence in their promotional literature.

I wouldn't get overly excited about a product without actual independent university testing.  I googled the info and it was basicly just a promotional pamphlet with tests done by cooperative extensions, whatever that means.  I realize that cooperative extensions are connected to universities but they are not used to conduct research as far as I know (which in this case, isn't far).
