Anyone tried Zerorust? http://www.zerorust.com/

It's supposed to be as good as POR, but without all the methylethylbad****, so it comes in aerosal cans and even colors, and a clear. I spoke with a guy at their HQ and he said the state of Oregon is using it to repaint all their metal bridges and that Cal Trans here in CA is painting all their dump boxes with it.

Regarding the POR floor repair, I saw a nice sample of it at a POR vendor booth in Portland, OR on Labor Day. The guy had a section of floor out of a car. Typical rusted through in areas......not missing huge sections. Anyway, it was fantastic, and hard as steel. I was very impressed.
