Horny stuff! Water pearls really nice. But beware: work best with rubber gloves, otherwise the hands are impregnated with the same. Have 2 days to scrub to get the water back to the fingers :-)
I used the product on the sprayhood. I washed it and let it dry as described in the product description. I did a test on the bottom corner. So far, nothing bad happened. In order to rub the sprayhood with the waterproofing, I laid it on the foredeck. Instead of 5m2 as described, it only covered 2m2. But now I got a nasty surprise when I wanted to put the sprayhood back on and found the pattern from the deck covering on the other side. My white sprayhood is now really dirty. I've tried different cleaning products. The stains won't come out. I never had any problems with the old waterproofing product from Yachticon. Sorry, but that nano stuff is the worst.
