Fluid Prevents Rust, Yet Won't Adversely Impact Welding Process


RP6 Weldable Rust Preventative Fluid, a new, innovative oil-based fluid, provides up to six months of indoor corrosion protection by preventing rust on ferrous metals, while not adversely impacting the welding process.

It is an ideal solution for welding applications in heavy fabrication, automotive, steel storage and agriculture – any welding application where raw materials may be subject to corrosion prior to welding.

The weldability of RP6 has been verified through rigorous third-party testing. Coated metal samples were welded, scored and X-rayed. The analysis determined that the use of RP6 did not result in any contributable instances of welding-related defects. Metals treated with RP6 require minimal cleaning prior to welding.
