3M Weld Thru Primer
Weld-Thru II – 5917. A sprayable, weldable, corrosion-resistant coating designed to prevent corrosion from forming between two welded metal surfaces.
Additionally, this product can be used to prevent corrosion on metal surfaces that will not be receiving any further treatment – i.e., body filler, primer, paint, etc – . However, for non-weld mating surfaces, products such as primer/paint, 3M undercoatings, or 3M Rust Fighter I will provide a higher level of corrosion protection.
Dries fast (15-20 minutes) with minimum spatter. Meets MIR requirements.
