"Friends abroad swear by this rust treatment. Totally different to Vactan. It doesn’t turn rusty steel blue/black, but claims to penetrate the rust, drive out all moisture and prevent further rusting. It can then be overpainted and even ADDED to any oil based paint to protect the metal and also “ease” the application by extending the flow and drying times. Anyone used it? \n \n"
