Try "Future Premium Floor Finish", $6, from the local hardware
store. Quoting from "Make Magazine, Volume 02":
Johnson Wax sells Future as a floor polish, but it's really a clear
acrylic paint. Put it on a clean, reasonably smooth, non-porous
surface and that surface becomes shiny. I use it on model rockets to
protect the decals and make a slick aerodynamic finish, but you could
use it on all sorts of projects.
Future thins and cleans up with water. I apply it with a slightly
damp foam brush, but I've heard of people using it with an airbrush.
It's best applied on hot, dry days; humidity causes it to fog up.
Future cures hard enough for a new coat after a couple of hours.
After a couple of days, it dries hard enough to be buffed and
polished with a clean, soft cloth.
