I used a two part epoxy many moons ago; held up pretty well under hobbyist use. Some of the newer stuff is better tho.
That being said, it is slicker than normal when wet, and if you live where its humid, it will 'turn wet' on its own some days... hence, flakes/granules/etc are to berecommended to give some surface irregularity and aid in traction.
Not only does the coated floor look nice, but it makes clean up much easier and doesnt stain easily. A light colour makes the room seem bigger and small parts/hardware that try to escape are usually easier to find also. But remember - prep is king. You cannot over clean...
