Should be oiless,they were used in dentist office's to run the dental hand tools that went in to the mouth..don't think you would want any oil to get in your mouth! Wife's cousin owned a dental lab had four of them seams he had one go bad in 20 plus years....good quality units.. yes you can paint with one but it's going to be limited to air brush or spot panel, it probably won't carry anything else.

Good Luck
