Concrete floor sealant (Recommendation needed)

[varmint]

When I had my shop built about 11 years ago, the slab was poured in the late fall. In the early spring (Maryland, so winter isn't like up north, but still we have winter) I did the muriatic acid wash (easy to do, if you can open windows and a garage door) and when it was rinsed and dry, I applied a two part epoxy, I forget which one, but it rolled on easily, and I did a second coat. Ever since, I have been totally happy with the results. When I splatter paint or glue, it scrapes right up without damage. And, spilled oil during oil changes cleans right up. I have used concentrated cleaner and water rinse a couple of times to clean up nasty oil stains, and never has the finish been damaged by anything I've done to it. Needless to say, the light gray color is easy to work on, and sweeping up is a snap. Unless you're talking about thousands of square feet, I'd say epoxy is the way to go.
