Garage floor covering? What works best?

[Hawkeye]

I know this topic has been discussed bofore, but I can't find any of the previous threads. Can someone please help me find them or what have you guys used for garage floor covering/painting/epoxy that has favorable results? I am gong to epoxy my floor in my garage and I would like to use a product that has proven itself. My floor is about 5 years old and in good shape. Should only need some minor cleaning prior to coating it. Please let me know what you have used and liked. Also, let me know what you have used and don't like.
Thanks,
Marty
