The product was invented by a German Company, Nanopool, and was called Quantum Liquiglas.....  They promised over and over it coming to market, but it never did....  I tried to get a sample in 2010, but it didn't happen.  I think the original product had derby possibilities as a bore coating.....
Rustoleum picked up the product somehow and now it is NeverWet, but I think its current purpose and application may have pulled it away from being a derby product, but I don't know....  I am not going to spend the $20 to find out.
You can stencil cool shapes and stuff on your driveway and when it rains the kids will love how the shapes magically appear/images/boards/smilies/smile.gif
