There are many types of airless sprayers, some very good, others are crap.
What do you have?
Poly would have to be thinned to spray, but it can be done. Lacquer is
another option.
Brushed poly can be done with three coats. The first thinned about 20%, the
other two about 5%. Let the last coat dry for two weeks, then sand with 400
grit, 600 grit, then polished with pumice and waxed. Time consuming, but
makes a very elegant finish if done right.
