ArdWrknTrk Posted May 10, 2023 Share Posted May 10, 2023 Another thumbs up here for Ospho! Man I love that stuff, and we get all the rust here...same as all the worst US states from Michigan to Upstate NY and New England. I have done a couple rusty Bullnose frames with Ospho, but also brake drums and other odds and ends. I think the stuff is brilliant! Remember that Ospho was just a Dupont trade name for the product, just like Lucite for acrylic sheet or Lexan for polycarbonate was before they sold them off. Kleen-Strip is the same green liquid for 1/2 the price (and a little goes a long way when diluted) Plus it should be available at the big orange box nationwide.
