Anybody have first hand experience with this stuff? http://picklex20.com/faq/ I used it before painting the columns on our porch a couple of years ago, and there's no sign of rust coming back through. Refinishing a bicycle for my daughter, and used it to on a couple of rusty spots. Wondered how it does in automotive applications, and whether it has a place on my fenders... Thanks y'all.
Yes I used it don't know long-term but from the research I've done supposed to be great stuff most people on the East Coast use it
