They recommend using vegetable oil to thin Fluid Film. They recommend against pump type sprayers so I'm not sure how a Maddox fits in. Perhaps mineral oil would work, paint thinner I think would separate the fats & oils in Fluid Film.



Those guns you use with the bulk stuff are actually undercoat sprayers with a large orifice, more like spitting a stream of globs of the stuff than an aerosol.

I did not know that. Sounds great! If peanut oil works, then I'll use left over oil from making french fries. It'll at least help improve the lanolin smell of FF :D

I also appreciate their website specifically uses the term thixotropic. FF does get thicker when it sits and has no shear forces acting on it. Though my understanding of thixotropic fluids makes me think shear forces have to be continually applied for the fluid to maintain the lower end of its viscosity. Still I'll give mixing it a shot.

The refillable type sprayers I'm thinking about, like the Maddox, are pressurized to (let's say 90 psi), what I expect is much higher than a "pump sprayer" could achieve. I suspect pump sprayer's low operating pressures are why FF recommends against them. Just too thicc for the low pressures to overcome viscous losses especially through the small orifices most pump sprayers have.

So maybe by thinning the FF with veggie oil, shaking it, and/or using an undercoating nozzle tip a refillable sprayer could be made functional.

I don't need nor want a perfect aerosolized delivery method. I'd just like something more convenient & affordable than the compressor hose nightmare and the store reliant 11 oz cans.

i would be afraid that mice might try chewing on my coating...hopefully it would kill them, but they love our veggie plastic coated wiring
Peanut oil had got to be attractive to mice. Fluid Film is lanolin so I bet it's already attractive to animals. Never really thought about it but do your tires happen to smell like wolf pee?

I was thinking bears when you head to alaska. Smelling like french fries and burgers are what killed the cook behind the Glacier Inn.

@allen.wrench - not that 16 ounces is sufficient for your project but noticed Safeway has 99% IPA for $2 or so. Only alcohol, no other ingredients active or inactive listed. This is a much more manageable size for cleaning electronics, though.

I might have to pick some of that up while it's still available. Usually 91% is the highest concentration you can get outside of a chemical supply/lab supply place. When working with really high concentrations like that up to reagent grade, it become quite hygroscopic and doesn't stay that high for long as it adsorbs atmospheric moisture.

Indeed, the one I go to had two on the shelf and now have zero. True statement about absorbing water, I use a little squirt bottle on the bench and keep the mother bottle capped and bagged in a Ziploc freezer with a couple of desiccant pouches. I sometimes get ambitious when I re-fill the working bottle and vacuum bag but I figure the original bottle (notably with a seal) didn't allow evaporation or water absorption so I'm just adjusting for what *might* make it in/out under the cap, which I doubt is much.
