I worked for a rental company that refurbished equipment. We painted some big stuff. Used a Graco airless sprayer. Worked really well. I have a nice one myself. Been thinking of employing it on some of these stupid big jobs. Overspray is minimal too. Layed out some nice paint jobs. Poor kid working for me was a mule. Up and down on manlifts and scoffolding. Felt sorry for the kid.
