Wow. Sounds like a lot of ugly, caustic chemicals in this multi-step process. I would achieve the same results by wire wheeling the rusty nuts (held by vice grips). Then I'd string 'em up on a coat hanger and lightly brush with Bill Hirsh Miracle Paint (which I prefer over POR-15). Let them dry overnight for a semi-gloss black. Or if you want to get creative, wait until the Miracle Paint tacks up, then rattle-can spray them silver, cast color or whatever floats your boat.
