Morris Workshop PRO MD-4 Penetrating Fluid & Water Displacer 5L

Morris Workshop PRO MD-4 is a penetrating fluid and water displacer for freeing seized, rusted parts and drying out wet ignition and electrics. This is the 5 litre workshop can, the bulk version of the MD-4 aerosol.What it does Frees seized parts: very low surface tension lets it creep into rusted threads and joints, then dissolves and lubricates so parts come apart Displaces water: clings to wet metal and pushes moisture out Protects: leaves a light oil film that guards against rust and helps reassembly How to use itWire-brush off heavy scale, rust and paint first. Apply by brush, dip or a refillable trigger or pump sprayer, then leave to soak for as long as you can – overnight for badly seized parts. Ideal for restoration work on old vehicles, trailers, plant and stored kit.Typical properties Appearance: straw-coloured liquid Relative density at 15°C: 0.850 Kinematic viscosity at 40°C: 2.46 cSt Closed flash point: 50°C – flammable, keep away from heat and sparks Quick answersIs this the same as the MD-4 aerosol? Same MD-4 fluid, sold in bulk. For quick damp-start sprays on plugs and leads the 400ml aerosol is handier.Is it a long-term lubricant?
