Morris MD 4 Penetrating Fluid Aerosol 400ml Powerful Rust & Corrosion Remover

Morris MD-4 is an effective, damp start and penetrating fluid with outstanding corrosion protection properties. When applied to wet parts the chemistry of MD-4 has a powerful attraction to the underlying surfaces and this completely displaces traces of water. Therefore this product is particularly useful as an engine damp start. Using the aerosol version, a short spray on to the affected parts will displace any wetness and prevent voltage breakdown, allowing the engine to be started again normally. MD-4 is also an effective penetrating fluid for freeing all seized and corroded metal parts.
It has been designed with a very low surface tension, which gives it excellent penetrating power, and this, coupled with superior solvent and lubricating properties enables the most inaccessible corroded parts to be speedily dismantled. The residual oil film acts as a rust and corrosion preventative on the disassembled parts and helps reassembly.
