Aero-Etch Aerosol Propellant is specially designed for exclusive use with Aero-Etch sandcarving kits, providing a portable air source for cleaning, refining, and surface-level engraving — without the need for an air compressor. Each canister of propellant delivers up to 55 PSI of propulsive power when connected to our patented Aero-Etch Sandcarving unit and 30" Hose and Stylus. This is ideal for: Surface etching on glass, crystal, stone, and other materials Polishing and cleaning surfaces prior to painting or coating Producing decorative sandblast effects such as frosting and shading (effects not possible with acid etching or etching cream) To achieve full sandcarving capability, including deep carving, pair your Aero-Etch Sandcarver with the Aero-Etch Compressor Adapter and your own air compressor (up to 75 PSI). Sizes Available: Single Canister (12 oz): Perfect for smaller projects or touch-ups. 2-Pack (12 oz each): Keep extra on hand for longer engraving sessions.
