The decorative metal spray process consists of fine metal powders mixed with binders, resins, adhesives and hardeners to make a sprayable liquid that creates a metal coating that is both beautiful and durable.
The industrial spray process uses an electric arc inside a spray gun to melt metal wire; high pressure air forces the metal particles onto surfaces to create a strong layer of metal that can be machined, plated, or to apply a protective corrosion control coating. One specialty is to restore old automobile pot metal for re-plating.

I'm thinking you want the industrial process.
Otherwise it's just paint.
