MD-4 is a 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. This product is particularly useful as an engine damp start. If the aerosol pack is used, 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. Coupled with superior solvent and lubricating properties, it enables the most inaccessible parts to be freed. The residual oil film acts as a rust and corrosion preventative on disassembled parts and helps reassembly. As a damp start, one short spray (aerosol) of 2-3 seconds on the plugs, leads, and distributor cap will displace moisture and allow starting. As a penetrating oil, heavily corroded and seized parts should first be freed of scale, rust and paint by wire.","attributes":[{"label":"General Product Group","value":"Oils & Fluids"},{"label":"General Product Type","value":"Lubricant"},{"label":"General Size","value":"400ml"},{"label":"Variant Id","value":"272808"}],"image":"https://b69270dd6ab1.blob.upstash.io/oracle/oro2u/90-551/af2476917d1c4cce.jpg","images":["https://b69270dd6ab1.blob.upstash.io/oracle/oro2u/90-551/af2476917d1c4cce.jpg"],"description":"400ml MD-4 Maintenance.
