The designation "Portable" implies more than just size; it implies a new standard of accessibility for corrosion protection.
For construction crews working in rainy conditions, a portable CM352 spray in every toolbox ensures that hammers, saws, levels, and drill chucks are protected overnight. Unlike WD-40 (which evaporates quickly), CM352 leaves a lasting barrier. 400mL aerosol |
