Re: Super-Durable Material Made from Wood Waste is Stronger, Cheaper, and Lighte...

Towards the nd of last year, someone (maybe Jerry?)  posted about a spray on product that repelled water on anything, even electrical things.  Maybe put these two products together and you would have something unless the water repellant  product was just a mirage.  I thought it was to be on the market this summer so maybe it is a mirage.
