The builder is using Tuf-Flex on my upper decks. http://www.classicsystems.net/tufflex.php It is a rubber compound that is spread out, leveled and then let cure. It can even be used to fair very uneven decks. On the top layer, chopped rubber granules are distributed on the top and they merge with the top layer to give a non-skid, but easy on the feet surface. I've walked on it bare feet in the hot Florida sun on a steel deck and found it to be very comfortable and sure footed to walk on. -Wray you wrote>I am getting ready to redo my upper deck and was wondering if any one out there knew of a really good coating for the upper deck of a steel trawler?
