Clear Finish over Paint

[Mal F]

I have painted some old paper finish woodgrain random groove ply sheeting (about 1/8" thick) using the following products
Zinsser Bulls Eye 123 Primer Sealer (one coat)
Dulux Wash & Wear 101 Super Acrylic Low Sheen (two coats)
The Dulux paint has been colour matched to match Wilsonart Panelart Double sided MDF, colour - D14 Port with a Matt finish.
The paint finish does not appear to be tough enough to withstand the traffic area. It is in a rumpus room and bar area.
What I was thinking was that I may be able to put a hard clear finish over the paint work to make it more durable.
Something in low sheen or satin finish.
Preference to water base rather than oil base but not essential.
I was considering Cabot's Crystal Clear but it did not get a good report on another thread.

So what do you think?
Is it feasible?
What other product would you recommend<

Thanks,
Mal

The cabot's clear floor (not the crystal clear) is water clear and extremely hard

Bob,
Thanks for your reply.
Are you referring to the CFP Water Based in the flooring section at the Cabot's site?
