I used this over a year ago on my aluminum floor flatboat and its still as good as the day I put it on. and I used the heck out of it and drag ice chests and tackle boxes around at it never wears on the surface at all. it goes on very thick (like 1/8" thick) so it does take about a month to get fully hardened all the way through so you have to be careful not to drag heavy stuff around before it has 3 or 4 weeks to fully harden solid.

if you paint on metal use self etching primer first.
it stays nice and cool and even in direct sunlight.it doesn't get hot
home depot stopped selling it by the gallon and just sells the 4 gallon cans but you can find it other places. my 17x52 flatboat took 1 1/2 gallons to do two thick coats of floor front deck and sides
