Blaster PB Penetrating Catalyst Penetrant 18 Oz.

The PB Blaster acts as a powerful, concentrated catalyst to release the surface tension of frozen parts. Then it converts into a nonevaporating lubricant to protect against further rust and corrosion. Penetrates fast into hard-to-reach cavities to free stubborn, rusted, or immobilized parts; nuts, bolts, screens, joints, pipe threads, and more. Contains no dangerous vinyl methylene chlorides, gasoline, kerosene, fuel, or cheap oils.
