Well, airless sprayers get such bad rap around here (from reading other posts, everyone says throw them in the trash) so figured I'd post my experience.
I roll/tipped my 21ft trailer yesterday with an (unthinned) alkyd enamel - took about 3 hours for 2 coats, including using a brush for the detail work at the seams and crevices that the roller couldn't get. It looked OK, no sags. I did about 1/3 of the hull on my Starcraft for giggles, it took about an hour (2 coats, and needs another). Very achy last night.
Today, put the same paint in my new-in-the-box airless painter and tested it on some cardboard. Looked good, so didn't change any flow settings. Painted the whole trailer, including all the nooks and crannies in about 10 minutes. Took 15 minutes to clean up though. Paint has a few sags in it - I'm sure it's from operator error though - not moving fast enough. I'll work on my technique.
Conclusion - I'll definitely use this in the future to paint my boat instead of rolling.
After painting 4 motorcycles and a truck with alkyd enamels, I know the more it's thinned, the less gloss it develops (without wetsanding/polishing - that's a whole other route). An airless sprayer is the only way I know of to spray unthinned paint. I've only used high pressure siphon guns in the past (and many of them, under different pressures, and different amounts of thinning).
Plus, they make that cool buzzing noise that echoes through the neighborhood.
