Hi-tech components make this the only sprayer that stands up to most solvents and acids. Chemicals that destroy ordinary sprayers don't harm SprayMaster. Powerful sprayer dispenses more than 2-1/2 times as much liquid per stroke as standard sprayers. Saves time and effort. The nozzle adjusts to a mist, spray, powerful stream, and anything in between. The extra-long trigger is easier to squeeze. Opaque silver bottle protects light-sensitive chemicals. A narrow clear window stripe helps use the graduation and dilution scales.
