What's the best way to store parts, Cosmoline spray? Options

[jsaum]

I have two transmissions and a couple of spare motors that I want to break down so I can store them in the crawl space under my house. The wife says the garage needs to get cleaned up! It stays dry but there is a lot of moisture in the air what is the best way to keep the cases from corrosion? I was thinking cosmoline spray then putting the parts in heavy duty plastic bags and boxing them up. Is there something that's easier to clean up than cosmoline?

Wd40 in ziplock bags.

No way would I put them under a house. . just asking for corrosion and rust. I've pulled out parts stored in damp areas and the pitting and corrosion rendered them useless, especially if on any mating surfaces or bearing surface. Better on shelves in a dry garage or attic

spray with gun preservation stuff, then wrap in cloth and spray cloth full too. After that put it in a vacuum heat sealed bag. (food sealer type)

How long and how damp?
Protective spray (NOT WD40) and well wrapped (air tight) is probably good for most situations.
Make sure the spray says on ALL machined surfaces.

Long storage or very damp, I would use the soaked cloth as suggested.

I don't think you need "Vacuum sealing" but would probably use packing shrink wrap over the bag to compress out some air and keep it from "Breathing".

Also "assembled" is better than disassembled as mating surfaces are mated.

I found some tool and die long term anti rust spray online. I'm going to break the transmissions down and use the spray on them. I'll bag them up and store the housings in the crawl space. I'll store the rest of the gears in the garage. I've had some engine tins, axles and other parts stored there for over a year and they're ok so far. I'll keep a close eye on everything. I'll break the engines down to short blocks they should be easier to store in the garage.

Boeshield T-9 it was designed to do just what your wanting to do, except I am sure they did not think of a humid crawl space.

Spray on, let dry, bag in a vacuum seal bag, more than likely a forever job.

"Boeshield T-9* was developed by The Boeing Co. for long-term protection of aircraft. Their research proved that none of the Teflon, silicone, or synthetic sprays held up for long when exposed to a corrosive environment. So they engineered a new product designed to: Penetrate deeply into fasteners and fixtures. Displace moisture and attack existing corrosion. Dry to a clean waxy film.

Lubricate and protect all metals for months. T-9* will also loosen rusted parts and will not harm paints, plastics, rubber or vinyl. Corrosion is a very important factor in prolonging the service life of airplanes. A significant advance in corrosion-inhibiting compounds has been made by the Boeing Company and is now being manufactured and sold, under license by PMS Products Inc. Boeshield T-9* is effective because of it's excellent water displacement, penetration and protective film development. The resulting coating will outlast competitive treatments and exhibits excellent results in salt spray exposure, "EXCO" immersion, and di-electric current tests. Boeshield T-9* also meets all flammability requirements of Federal Aviation Regulation 25-32 after the solvents have evaporated, and is effective from -40 degrees to 250 degrees F. Boeshield T-9* has a mineral spirit base and can easily be sprayed with a variety of equipment. All that is necessary is enough pressure and nozzle size to form a mist. Simply wet the surface and the desired coating will form after 5 to 7 days of drying.

Excessive spraying will only increase puddling and extend drying time. Once on the surface, Boeshield T-9* has excellent penetrating and moisture displacing properties. Using capillary action it will cut through and stop existing corrosion, find its way into lap joints, seams, and around rivets, and eventually weep out the exterior. However, this activity stops after a limited time (usually 5 to 7 days, depending on temperature and humidity) at which point a waxy film develops in all areas. In this way, the coating will stay put for much longer than the all liquid treatments, eliminating the continual weepage and cosmetic problems associated with them.

When reapplication is necessary (usually 3-5 years depending on service and exposure) the existing coating will be re-liquefied and resume its penetration and weepage, again only for a limited period. Boeshield T-9* also is non-conductive and will not cause short circuits in electrical systems. However, care must be taken to keep away from areas where point contact is required, such as keypads on electronics. Boeshield T-9* has a mineral spirit base and contains no harsh solvents such as MEK or Trichlor Ethylene. Therefore, it is safe to use around most paints, plastics, rubber, vinyls, wiring, and many glues. It is very effective for rust proofing steel tubing on fabric covered aircraft, but should be tested on the exterior skin prior to application to insure no degradation of the material or lap joints takes place. Boeshield T-9* is available in 1 and 5 gallon pails, and both 4 and 12 ounce aerosol spray cans.
