I'm leary of that as the only way to do that right is get the pros in, grind everything down, put in way expensive epoxy, worry about adding non-slip sand or flakes into it, and then after all that money, still get rust spots on it and have to work hard to keep that clean. cost for 3 stall garage is probably north of $5000?
I got a 3 car garage floor coating for less than half that price.
This is what mine looks like...it's worked our well.
ps: As others have stated I'd avoid the paint too.
