Exhaust manifold restore

Has anyone ever used Rust bullet or even heard of it?

I use it for suspension, and inside/outside of the undercarriage , but I do not believe it is really rated for manifolds.

just checked the website, I think you would be on the ragged edge...but if you do it, let us know how if works!
