$5.99 EA

PB™ BLASTER® Penetrating Catalyst uses capillary action to creep up and around and into hard to reach places to quickly break free surface tension rust and corrosion. It is the original nut and bolt buster. Rust corrosion, sticking and squeaking problems are eliminated. The lubricant also displaces moisture and does not evaporate so that surfaces remain coated and rust resistant.

The world famous PB™ Penetrating Catalyst is more than just great. PB™ is formulated to have a unique capillary action that allows the lubricant to pull itself uphill and into tight cavities to fight rust from all angles. The penetrant saturates rust to break the surface tension and quickly free the rusted or frozen part.

PB™ is a rust inhibitor. The special formula displaces water and does not evaporate leaving a concentrated co-polymer penetrant coating on surfaces to lubricate and resist future rust.

Developed in 1957, it has been time tested and proven to perform. It is safe for all metals.

PB™ Penetrating Catalyst can be used in numerous applications such as starting wet engines, stopping rust and corrosion, lubricate fishing reels, and guns, farm equipment and industrial applications, electrical and relay equipment, and to prevent the sticking of wheels due to galvanic corrosion.

Rusted bolts, anything rusted or corroded. This stuff eats right through it. Only penetrating oil I will ever use

Works as expected. Great price! Tried WD-40's NEW PENETRANT and it doesn't even come close to how well PB BLASTER works. Will never use anything else. Can't wait to try the other Blaster products.
