If you're going to be driving equipment in there and doing heavy work I wouldn't spend $1500 on coating. Have the concrete polished and then just put a coat of wax on it. You'll need to redo the wax every other year or so but it will hold up pretty well and it is easy to sweep up.
Interesting suggestion, thanks. But what happens when oil, gas or solvents inevitably drip on the wax? It'll pretty much instantly dissolve (and likely stain the concrete permanently).
