Teardrops n Tiny Travel Trailers

I saw a video of a guy building a kayak, he covered it with canvas and then put 3 layers of this Robsons rt-10 stuff over the canvas, then sanded and painted over it. Came out really nice! Has anyone heard of this stuff or the Robsons brand? They make many products that could be an answer to many questions here on the forum. http://www.robsonthermal.com/products-and-data-sheets
I couldnt find a price on anything or an outlet to buy from. I may have to call to get a price.

Let us know if you get pricing, especially on canvas....52" would be nice.
