I made up a sprayer years ago out of a old propane tank and a sandblast gun. Used it for bar and chain oil , with a splash of WD-40 to help it flow. Welded in a dip tube , filled the tank through the top where the LP valve was, screwed in my bushing to a 1/4'" air fitting, regulated about 30psi to the tank. Ran the oil out of the dip tube through a hose to the gun with a 1/4 turn valve and ran line air to the back of the gun. That rig will really spray some oil ! Wasn't sure how it would do with Fluid Film as I had to scoop it out of the bucket and jiggle it through a funnel to fill it. Works just fine! Bar and chain oil was the gold standard here for years but I guess it isn't as environmentally friendly as the sheep dip !
