Penetrating Catalyst

The PB B\'laster 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.No. PB-TS: 5 oz. aerosolNo. 16-PB: 12 oz. aerosol
