Cosmoline on a Transmission? Anyone? Options

[detoxcowboy]

I just read in the vendors section of Cosmoline being used to coat a transmision for protectiveness after being cleaned.. Has anyone used this before? How does it hold up? (apperently it is used for fire arms and automotive, available in aresol and bricks)

Curious as I recently replaced my transmission and now have a very cleaned case..


Cosmoline is the trade name for a generic class of rust preventatives, conforming to MIL-C-11796C Class 3, that are a brown colored wax-like mass; have a slight fluorescence; and have a petroleum-like odor and taste (as detected when working with it).

Chemically, cosmoline is a homogeneous mixture of oily and waxy long-chain, non-polar hydrocarbons. It is always brown in color, but can differ in viscosity and shear strength. Cosmoline melts at 113-125 °F (45–52 °C) and has a flashpoint of 365 °F (185 °C).

Its most common use is in the storage and preservation of firearms. Previously, cosmoline was used to preserve other items. Entire vehicles can be preserved with cosmoline.

The thing with Cosmo is that when you actually put the thing into use that has been protected with it, all the cosmo has to come off. Be it firearms or cars or whatever.

And removing cosmoline SUCKS. Especially on old rifles where it has soaked into the wood. Leaving it on your transmission would cause it to slowly melt and drip on to your heat exchangers. Which would then cause smoke and stink and stinky smoke and maybe fire. it will also drip on your garage/driveway causing slick spots.

But it does to a good job at stopping rust while in storage.
