ah i smell what you're stepping in now. i use lacquer either sanding sealer (if going clear) or undercoater (of the desired color) followed by the top coat. some people use poly (urethane or acrylic) but it's just personal preference as either works fine, lacquer is faster and it's what i spray 99% of the time in my other woodworking jobs.
EDIT: both do need ample off gassing time and again lacquer is the winner here too. you can also run the incubator to speed this up (no it won't ignite the fumes), just make sure you keep all the vents open to allow good air exchange.
