Click on the photo to see the results of when I tried ACF 50 on a rusted gear leg. I was honestly astonished by the results. If I can do a decent deal with the suppliers I may sell it, but at the moment you can get it on Amazon - This and Acrylic Werks are two of the very few products that l think live up to their claims. It is about £15-£20 a can. Dave Doyle
