Graco says its PerformAA is the only air-assist spray gun with material-specific air caps: Wood Lacquer (WL) for applying lacquer and topcoats; Low Viscosity (LV) to evenly disperse stains, sealants and toners; and General Finishing (GF), to atomize enamels and paints at low pressures. The PerformaAA is ideal for use in finishing cabinets, flooring, furniture or trim, the company adds.
