MSI Buster | Foaming Penetrating Oil for Rusted & Seized Parts

MSI Buster is a professional-grade penetrating oil engineered with exclusive foaming action to break through rust, corrosion, and seized components faster and deeper than traditional penetrants. The high-strength lubricating formula expands as it foams, allowing it to reach deep into threads, joints, fittings, and stubborn metal surfaces that need loosening.

Designed for automotive, marine, industrial, and heavy-duty applications, Buster quickly frees rusted bolts, nuts, clamps, hinges, and frozen parts while reducing friction and preventing future corrosion. This foaming action minimizes runoff, increases contact time, and ensures maximum penetration for tackling the toughest jobs.
