Sportco in Fife also carries it, at least they did last time I checked, You might also give GI Joes a call to see if they stock the stuff. One hint, if Auburn Sports runs out of the small cans, ask them to get you the 1 gal. can. One hint, when you go to apply it, try and pick a nice sunny day, let the boat bottom get nice and hot, then apply. You'll
get done in half the normal time...
Good luck!!
