It is also excellent for fishing reels, guns of all types, knives, power and hand tools, electronic and audio equipment, model trains, slot cars, R/C equipment, watches, music boxes, fans of all types, locks and padlocks, bicycles, skateboards, roller skates, sewing machines, typewriters, and anything else you previously used petroleum-based oils or lubricant sprays on. Because of their nature, petro-oils and lubricant sprays leave sticky deposits when they evaporate over time. In contrast, Liquid Bearings is made using a process that re-arranges the structure so all the molecules are uniform in size, shape, and weight, an ideal phenomenon which does not occur in nature. It is custom-designed to produce the ultimate lubricant, with inherent performance characteristics vastly superior to any petro-oil, and it never evaporates!In your older items, it is fully compatible with all vintage and current oils, and will flush away the residue of the evaporated petro-oil. You will easily notice that anything you lubricate with it will immediately move easier with Liquid Bearings, especially if you have been using petroleum-based oil on them for years. It is completely plastic-safe for all plastics, and will not harm any painted surfaces. The bottle is top-quality soft LDPE, and the pharmaceutical-grade stainless needle allows the application drop-by-drop, very precise. We also provide BOTH the standard " needle AND the longer 1-1/2" twist-on/off needles, each with its own tip scabbard for leak-proof storage. We always offer a money-back guarantee!
