I had the pleasure of a gang of ducks (or some other bird with big poop) molest the bow of my boat. Mind you they didn't have the manners to just poop on the deck, but I think these were "gang ducks" as they smeared it all over the deck... I even think they wrote duck gang symbols in the stuff. The stuff ended up drying and I've spent an hour getting the crap off. What is in that stuff? I think there might be a market for this stuff as an industrial adhesive.
