Anti-corrosion Sprays

3M™ Weld-Thru Coating II is an anti-corrosion spray designed to be applied directly to metal surfaces before welding. The coating helps prevent galvanic corrosion and weld spatter from sticking to the metal surfaces. It is also designed to be heat-resistant and to protect welded joints from rust and corrosion. The spray is fast-drying, low-VOC, and can be used for both MIG and TIG welding. Click on the products below to find out more and easily place an order.
