There are a lot of options and it depends upon the finish you are using. Since this sounds like something that will sit outside you need to use an exterior and wood rated finish. If it were me, I would go with oil based.

For latex and heavy oil finishes I use a contractor grade airless sprayer because that’s what I have. You can use an turbine spray rig to do the same and it will also be good for interior finishes as well. All I’ve seen are HVLP so that helps cut overspray down.

Overspray is a real problem with all sprayers, some more so than others. The type of finish used matters as well. For latex, water based and oils like poly you are basically shooting glue. That is, the overspray can do a fine job of sticking whatever it lands on nearby together. For lacquer this isn’t much of a problem because it’s pretty dry when it hits, most everything else isn’t.

Spraying outdoors is fine weather permitting, you can spray in the sun but don’t let it cure in direct sunlight.

Drying time is generally less with spraying, the caveat being that you can put more on in a given amount of time so it might take longer – just because you put more on.

Spray finishing is definitely an art to master and well worth the effort – it does take some experience to get a feel of what can and cannot be done though.
