I used alot of that spray on bed liner this summer on both my boats and its holding up great. I rebuilt the transom on my lake boat and used the stuff as a final coat. Also used it on the floor, no problems so far. Fred Meyer seems to have the best deal on it, larger can for about half the price. Its in the automotive section. Just make sure your surface is prepped properly otherwise the stuff will bubble right up and not stick. Good luck.
