I would agree with Smokey.
Water based urethane. Dries faster than solvent base, most durable finish, easier clean up.
Depending on how big the piece you are finishing you can get it in spray cans or bulk in qts. or gals.
Get the spray cans with the fan type spray head unless you are spraying with a compressor. HVLP type sprayer works best.
You will need to sand lightly after the first coat to knock down any raised grain.
