Many people will not go anywhere without a can ofWD40. It is a great product and you will find it on this page. It is not the only God-in-a-can product that we stock, however. We also carry a similar product toWD40 called WD Lube (also on this page). (WD means water displacement).WD-40 is a light hydrocarbon oil with penetration properties useful for moving seized parts. It also works as a rust preventer by leaving a thin layer of oil on steel. WD-40 earned its reputation as a moisture displacer in the days when cars would not start due to condensation under the distributer cap. A further refinement is a product called INOX MX3. It does not contain petroleum or silicone based products and is indeed non-poisonous(the other products are not strictly poisonous, just obnoxious to taste) so much so that you can spray INOX near food. All God-in-a-can products have come a long way from their original automotive use. They have great anti-corrosion and lubrication properties, for example. They continue to find applications all over the place, but with modern ignition systems you can probably safely leave home without a can.
