My two cents:

I used Rustoleum 2-part epoxy, note there are two types:

one is water based.

the other is an industrial (non-water-based). I used the industrial (non-water based) on a new concrete floor. My local hardware store ordered it special for me. I applied two coats, one does not seem to look good on fresh concrete, perhaps new concrete absorbs more of the coating. Since April I have had heavy trafffic, tools, engine hoists, pallets etc. It seems almost impossible to scratch. Now for stains, I have not had a test yet, nothing leaking or spilled. The test will be our North-East winter with frost heaves, sub-zero temps, road salt and grit. I am pleased so far, reasonable in cost, easy to apply. Updates to follow. Good luck on your choice of a coating!
