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.

There are different types of cosmoline. The old stuff you used to heat up and apply, and it stays tacky for a long long time. The newer stuff that we use here is the Cosmoline brand, in a spray can. It does dry to a waxy hard finish, but it takes a couple weeks for it to really get to that point. LPS#3 dries as well, and may be a little less nasty than the cosmoline. I would worry about some chemicals on the case, since the case may be MAG not alum, this i'm not to sure about.
