urethane clear coat

has anyone tried using water based urethane wood floor varnish for model clear coat?

i'm not talking about floor polish, (like future), im talking about the stuff that comes in a tin, the actual varnish itself.
this is the newer, water based type not oil based. (it dries totally clear, not yellowish like oil based)

i have used it for other projects, and id imagine youd need to thin it a lot.

so has anyone tried it?

Could you post a picture?

many brands out there, this is the common one in australia
