Keeping a Flywheel from rusting....

circumstances lead to leaving a TR4 trans with flywheel in an unheated garage for the winter. What can I do to keep the face of the flywheel from getting rusty?....spray?..Grease???
 
Most likely it won't need anything at all as long as it's out of the rain. I've got a lot of parts, including flywheels, that were stored for many years in an unheated garage, with no damage.

However, I've been experimenting with a product from the folks who make PB Blaster, called "Blaster Corrosion Stop". It's basically just a spray grease with a solvent carrier that evaporates; leaving behind a fairly thick layer of grease. But it is readily available around here (Walmart, Home Depot, etc), inexpensive, and so far seems to work very well even on parts that are stored outdoors.

I've tried other products from various sources, but so far the Blaster product seems to be winning. YMMV
 
Another good rust inhibitor is LPS 3. It sets up as a soft waxy coating.
 
Personally, I don't like putting grease on parts like flywheels and brake discs because you've got to get all that grease off. What about a large ziplock with a couple of desiccant packs?
I also have several flywheels that have been crudely stored for many years with no rust at all (perhaps they had a little oiling from the rear main?).

Vegetable oil, and in a plastic bag?

Darn-near any kinda greasy-stuff will do, as all you're trying to do is separate the metal from the oxygen source.
 
the only time I have had an issue with cast iron rusting is in the spring when like my planer deck is very cold and spring comes with a very humid day and the cold cast iron will have moisture condense on it, On the fly wheel I would think about spraying a primer on the surface where the clutch goes and if you ever use it just sand the primer off. In fact I dont see why you couldnt prime the whole thing

I break out my trusty can of Cosmoline when I need it...
 
Or just keep the transmission indoors in the tub of the guest bath...which I used to do before meeting my wife.

It's what they use on aircraft that sit out in the weather...
 
I'd just spray it with a light coat of lacquer in a spray bomb. The just wipe the paint off with thinner when you get ready to use.

So how do you get the right kind? I bought a can that says "Cosmoline" but what comes out is more like WD-40.
 
I work in an ordinance foundry....make mortar shells for the military....Grabbed a couple of cans of milspec stuff...
 
Why not go to your local marine supply and purchase some anti-corrosion spray (like Quicksilver Corrosion Guard - check EBay too)? It's what you spray on your boat engine prior to putting it away for the winter. I'm sure it can be removed with Brake Cleaner or mineral spirits in the spring. Cheap and easy.
