I don't know the name in english, I was using a aquarethane product called "vitrifiant" in french (roughly translated "vitrifying"). It's used for wood floors, and give an extra gloss finish. The product itself is like acrylic paint, almost odorless, and fast drying.
I was usin it for pinball game field. Really, really gloss (everything reflects on the gloss surface like on a mirror).
It's the most glossy product I ever tried
