Morris Workshop Pro MD4 Penetrating Oil 400ml Aerosol Can (Similar To WD40)

Workshop Pro MD-4 is a high-performance multipurpose maintenance spray with superior damp-start, penetrating, and corrosion protection properties. It effectively displaces moisture, prevents voltage breakdown, loosens seized components, and provides long-lasting rust prevention.

This versatile maintenance fluid is specially formulated with low surface tension, enabling it to penetrate deeply into corroded or rusted areas, freeing stuck metal parts efficiently. Additionally, its residual oil film acts as a protective layer against future corrosion, making it an essential product for workshops, automotive repairs, and general maintenance applications.
