Picklex 20 any good?

Does anyone have any experience with Picklex 20?

It's "A combination metal surface cleaner, surface rust

remover, 100% rust converter (including mill scale),

conditions metal and provides a conductive metallurgical

protective coating for long term rust protection, all in

one application."

Is there a BETTER rust converter/remover out there?

Thanks.
