What Epoxy Floor To Get?

[68droptop]

I've looked at a ton of threads and I think I'm going to go with an epoxy floor. I just don't know what to get. The only thing I'm worried about is dragging a floor jack around. Will it scratch or chip? I know about using wood for the jack stands. How about welding and grinding? I'll use a blanket if I have to for that.

Thanks for your help.
