Without careful maintenance, it won’t be long before a spray gun starts spitting. Andy Charron explains here how to maintain your sprayer equipment, be it high pressure, high volume (HVLP), low pressure, or turbine-powered. He uses old toothbrushes and fresh toothpicks to remove gummy finish without damaging the gun. You need to take special steps for when you switch finishes, and lubricate anything that moves. He also shows how to clean the gasket, clear the air passages, and remove the air cap and fluid nozzle. From Fine Woodworking #136
