: I would like to use Dacron cover my skin on frame kayak. But I am not sure
: what to use to coat the Dacron to make it water proof. I thought of using
: epoxy but have heard that epoxy does not fully adhere. I have seen sites
: where people use polyurethane to waterproof dacron. But what if you want
: to use a color? Do I paint over the polyurethane or add coloring to the
: polyurethane? If anybody has any experince with this or knows where I can
: get coatings suitable for dacron, I would be very gratefull.
