Hob-E-Lube Workbench 7-PakPrecision lubricants for craftsmen This super-saver value includes all seven lubricants plus complete instructions that spell out precise applications and the exact lubricant to use. Be prepared. Know where and when to use which lube: nonconductive, nonstaining, penetrating.We all know the benefits to be had from keeping our model railway locomotives and rolling stock lubricated: smooth running, no squeaks, less wear on the gears and bearings, and potentially more reliable pickup of power from the wheels to the motor or decoder in locomotives. In damp environments, oil can provide some protection against corrosion of metal parts.However, the job that lubricant has to do can vary depending on where it is being used, and therefore a number of specialist oils and greases are available for specific purposes. It is better to use these specialist lubricants rather than use a general purpose oil for everything, although even that is better than no lubrication at all Woodland Scenics alone have developed 7 variants of lubricant, and thes are conveniently available in this pack. Not only do you save money compared with buying each lubricant individually, but you will have an ideal lubricant to hand for all your model railway needs. If you are unsure of which one to use where, there are instructions that will guide you.The contents are; Hob-E-Lube HL651 Dry Graphite Lubricant, Hob-E-Lube HL652 Dry White Lube / Lubricant, Hob-E-Lube HL653 Ultra Lite Oil, Hob-E-Lube HL654 Lite Oil / Lubricant, Hob-E-Lube HL655 Gear Lube / Lubricant, Hob-E-Lube HL656 Moly Grease / Lubricant, and Hob-E-Lube HL657 White Grease / Lubricant
