Gary, Super job, you're gonna love it! Epoxy products get harder as time passes. If you can, stay off about twice as long as the instructions require. When I know I'm about to abuse the floor, (centerstand, big hammers, etc.) I try to put down a sheet of cardboard to provide a bit of protection.
Chef, The ceiling is just "white steel" siding from the local lumberyard. Its a bright, clean, reflective surface that is washable.
