Wow, missed this one on the list a couple weeks ago. Been wondering the
same myself.
Ten years ago I laid down "Hard Deck", a two part epoxy after
*extensive* cleaning and etching of the floor. The stuff is made for
airport hangars. You have to be gentle with a floor jack on it, and if
you drop a fairly heavy tool like a breaker bar, it will gouge it. But
upon close examination the concrete below is usually gouged. Can't ask a
coating to hold up if the substrate won't.
It's held up a bunch better than some painted floors I've seen, Still,
I'd like something better. Unfortunately, or for the better, it's so
durable I think it would be nearly impossible to strip. The first epoxy
layer soaked in like a stain, the 2nd laid on, and the poly' on top is
*untouchable* by solvents I've seen rip up other floors. Got a little
oil spill or brake fluid? Throw some acetone, MEK, brake cleaner, etc on
it and wipe up. I WILL NOT budge. The company rates it as resistant to
"skydrol" which is some kind of aviation hydraulic fluid I have not used
myself, but assume is pretty harsh.
