Show rust and corrosion who's boss with this PB Penetrating Catalyst, 11 oz. from B'laster (16PB). It quickly breaks loose surface tension rust and corrosion by creeping up, around and in to hard-to-reach cavities.  It can also be used to lubricate squeaky or sticking machinery and parts.  It displaces moisture to combat rust and corrosion while the lubricating film remains on parts to help prevent further rusting.  Ideal for brake exhaust and suspension system jobs, it's perfect for use on rusted nuts, bolts and pipe threads. It's non-evaporating and saves you time and money by ensuring you won't have to burn off or drill out nuts and bolts or other expensive and time-consuming repairs. Perfect for use with engines, fishing reels, guns, shock absorbers, farm equipment, industrial and aircraft applications, electrical equipment and relays.
