The Microlon Oiler has been specially blended like no other oiler on the market today. The Microlons half micron fractured resin is custom blended to high-grade synthetic oil. When applied to any metal-to-metal contact point it starts immediately to work reducing friction and it is not harmful to plastics. The injector tip makes this oiler ideal for getting to those hard to reach places. Microlon Precision Oiler is great for crossbows, fishing reels, hinges, locks, chains, anywhere that typical oil is used.
