B'laster 11-ounce Penetrating Catalyst is designed to penetrate, lubricate, and prevent rust. It converts into a lubricating film after permeation and is fortified with chemistry to combat surface oxidation and rust. It can start wet ignitions and penetrate through wet or icy frost, while its intense wetting agent displaces moisture in electric relays. The new three-way delivery system/straw enables both pinpoint and broad-based application of the penetrant.
