3M Weld-Thru Coating II, 05917, 12.75 oz Net Wt/361 g, 6 per case

• CONVENIENT AEROSOL SPRAY: Fast and easy spray-on application boosts shop efficiency and productivity
• MINIMUM WELD SPATTER: Special formulation helps prevent shop damage
• PREVENTS COSTLY COMEBACKS: Protects bare metal panels and parts from corrosion after welding
• QUICK DRYING: Dries in as little as 5 minutes before MIG welding for efficient throughput
• ZINC BASE: Cleverly engineered to draw away contact corrosion and provide long-term substrate protection

3M Weld-Thru II is a convenient aerosol coating designed to prevent corrosion between welded metal surfaces. Featuring a zinc base that draws corrosion away from bare metals, it helps prevent costly comebacks due to corrosion at welds. Spray coating applies fast, resists weld spatter common to some weldable primers and dries in as little as 5 minutes, increasing shop efficiency and productivity.

Keeping Bonds Strong
By preventing corrosion between welded auto body panels, our 3M™ Weld-Thru II promotes stronger business between your shop and your customers. This coating protects against corrosion where untreated bare metal substrates are welded – its zinc base uses the concept of bimetallic corrosion to keep metal parts from degrading. Welds stay strong, parts and panels don’t corrode and you keep comebacks to a minimum.

Tough on Corrosion, Easy for Welding
3M™ Weld-Thru II also helps keep collision repair shops operating efficiently. Its convenient aerosol can makes it fast and easy to apply, and features an actuator tip that resists plugging even after repeated use. The coating dries in as little as 15 minutes when using a resistance spot welder and as little as 5 minutes for MIG welding, helping technicians work faster and maximizing throughput. The formula also resists weld spatter than can cause burns to technicians or shop equipment.

3M™ Weld-Thru II can also be easily used on non-weld metal surfaces with 3M™ Cavity Wax Plus 08852 and 3M™ Cavity Wax Applicator Wand Kit 08851.

Applying Better Science to Collision Repair
Our 3M™ Weld-Thru II coating is another example of 3M Science. Applied to Life™. It uses the science behind bimetallic, or contact, corrosion to draw rust and other corrosive effects away from untreated bare metal – keeping the bonds strong at the welds, and keeping the bonds strong between your customers and your collision repair business.

Trusted 3M Weld-Thru II

The 3M Weld-Thru Coating II, model 05917, is a reliable choice for protecting metal surfaces during welding. This product is designed to prevent corrosion on bare metal panels, ensuring strong welds and lasting repairs.

Its zinc base formulation draws corrosion away from the metal, reducing the risk of damage after welding. Using this coating helps shops avoid costly comebacks and maintain customer satisfaction.

Convenient Aerosol Spray

This coating comes in a 12.75 oz net weight aerosol can, making application fast and easy. The spray format boosts shop efficiency by allowing quick coverage of metal surfaces before welding.

Its actuator tip resists plugging even after repeated use, ensuring smooth operation throughout the job. The aerosol design supports productivity in busy collision repair environments.

Quick Drying Formula

The 3M Weld-Thru II dries rapidly, in as little as 5 minutes for MIG welding. This quick drying time helps technicians work faster and increases throughput in the shop.

When using resistance spot welding, the coating dries in about 15 minutes, still supporting efficient workflow. Fast drying reduces downtime and keeps projects moving smoothly.

Effective Weld Spatter Protection

This coating’s special formula minimizes weld spatter, which can damage shop equipment or cause burns. The 3M Weld-Thru II helps maintain a safer and cleaner work environment.

By resisting spatter, it also protects the metal surfaces during welding, contributing to stronger, cleaner welds. This feature supports both technician safety and repair quality.

Six Per Case Packaging

The product is sold in cases containing 6 aerosol cans, each with 12.75 oz net weight. This pack size is ideal for shops needing multiple units for ongoing projects.

Having six cans per case ensures a steady supply of coating for various jobs, helping maintain consistent protection across all welded panels and parts.
