PB B’laster® Penetrating Catalyst

Don’t bust your knuckles, bust your nuts

This PB B’laster® Penetrating Catalyst is the original nut and bolt buster. It quickly breaks loose surface tension rust and corrosion by creeping up, around and into hard-to-reach cavities. Plus, the lubricating film remains on parts to help prevent further rusting. It's ideal for brake, exhaust and suspension system jobs. This penetrant saves time and money by ensuring you will not have to cut off or drill out nuts and bolts or use other expensive and time-consuming means of repair. The preferred Penetrating Catalyst of professional mechanics and homeowners. 11 oz. can. Made in the USA.
