PB Blaster - A powerful penetrating catalyst designed to free up and break loose rusty nuts and bolts. It also lubricates and halts rust and corrosion. Formulated as a penetrant, not just a Water Dispersant.
The world famous PB Blaster Penetrating Catalyst is more than just great. PB quickly brakes loose surface tension rust and corrosion by creeping up, around and in to hard-to-reach cavities. It's ideal for brake, exhaust and suspension system jobs. Plus, lubricating film remains on parts to help prevent further rusting.
