Sure Shot sprayers are an inexpensive way to apply bulk chemicals like cleaners, degreasers, penetrating oil, solvents and lubricants. They use readily available compressed air, instead of flammable or dangerous propellants, and because they are reusable you don't have to worry about disposal of empty cans. The sprayers feature metal construction, brass nozzle and corrosion resistant working parts. They work with oil and solvent based materials. Sprayers have 32 oz. liquid capacity.
