Tank marking stickers and decals from The Scuba Doctor are the perfect way to correctly and safely label the contents of a cylinder.
Tech Tip — Perfect Positioning of Decals
Clean the surface of the cylinder to remove any deposits and old decals. On painted aluminium cylinders we recommend scraping any blistering or peeling areas to remove loose paint. If you use any cleaning solvent, keep it off the valve and neck; be sure to rinse with soap and water when you are done. Once the cylinder is clean, peel the backing off your decal, lightly wet the adhesive back with soapy water, and apply the decal to the cylinder. While wet, the decal can be perfectly positioned then allowed to dry. Once the soap evaporates, the decal adheres very well.
