Avoid costly come-backs and increase efficiency in the workshop, with 3M™ Weld Thru II. Apply our convenient aerosol coating to prevent corrosion between welded metal surfaces. Our coating keeps metal parts from degrading while resisting weld spatter. It dries in just five minutes, increasing productivity.
Increase workshop efficiency, prevent costly come backs and promote a stronger business between your shop and your customers, using 3M™ Weld Thru II. Our innovative coating harnesses the science behind bimetallic corrosion, with a zinc base that draws the corrosion away from bare metals, to prevent decay between welded metal surfaces. It keeps metal parts from degrading while resisting weld spatter common to some weldable primers. Tough on corrosion and easy for welding, our handy aerosol features an actuator tip that resists plugging, even after repeated use. The coating dries in just 15 minutes when using a resistance spot welder, and as little as 5 minutes for MIG welding. Technicians can work faster and more efficiently.
