As an avid fisherman my reels are constantly exposed to the elements of water, sand and an occasional trip to the river bottom. After coating my reel with the Microlon Precision Oiler my casting distance has increased dramatically and the reduced friction is amazing! Once a year I do a complete reel disassembly and remove all original grease and use only the Microlon Precision Oil. One flick of the wrist and the reel seems to spin forever.
