You can make your own version of Fluid Film with some pure, unscented liquid lanolin, a spray bottle and 99% isopropyl alcohol.
A solution of 1 part liquid lanolin and 4 to 5 parts parts 99% isopropyl alcohol (4 oz of liquid lanolin to16 - 20 oz of isopropyl) works well. When mixing you may find that the lanolin mixes better if you warm both the alcohol and lanolin in a bath of warm water to about 105 - 110 degrees F before mixing. DO NOT WARM EITHER OF THEM OVER AN OPEN FLAME! Once the solutions are warm, pour together, mix thoroughly, allow the mix to cool (mix occasionally as it cools) and store in an air tight container to prevent water from being absorbed by the isopropyl.
