Stop throttle shafts from rusting

A ways back I thinned out my throttle shafts on my carburetor but I never put the carburetor back together because other projects dog piled on me.
I checked them out last week and where I had thinned the shafts out surface rust appeared because they have been sitting in my garage unprotected.
How do I stop them from rusting?

A thin film of oil will do wonders to prevent corrosion. Or you could nickel plate plate them if you're feeling spendy.

With the oil, a cutting or a motor oil will do?
Hmmm, nickel plating is a bit too far out there at the moment. I will keep that in mind. thanks.

Actually, a good gun oil would be ideal, but engine oil, general-purpose mechanical oil, or even wd-40 would do the job.

Point is to drive moisture out & then prevent moisture from getting to the metal. Most any oil will do that well.

why is nickel plating spendy? find a nice DIY video and buy a nickel rod and the $5 worth of other materials needed to do it, although time consuming it isn't an expensive process to do. the same applies to anodizing, zinc, nickel, copper and various other chemical processes which simply involves a etching agent(acid), electrolyte liquid and a power source. this might be preferrable anyways because it will build up the worn out area and reduce shaft slop. the downside is that platings are weak and malleable, not a good surface for wear.

it's going to rust once you put it into service anyways(if not treated with an anti corrosion plating), aside from the actual bearing surfaces.

the largest detriment though is of course now having hazardous waste sitting around once you're done.. which you could turn into a reconditioning station for other people's parts!

It's spendier than a squirt of oil.

chrome is in a slightly different ballpark though, with the major carcinogens involved and all.. lol

chrome would be a good plating for the shafts however, since it is extremely hard and wear resistant but unfortunately far from a DIY process unless you don't mind the EPA putting a bubble over your house and throwing you in prison.

I'll do nickel at home; electroplating small stuff is easy enough. It's great for rustproofing underhood steel hardware that can't be easily replaced. Hardest part is getting the target 'metallurgically clean". But I got all the stuff I need already.

But for chrome I farmed it out to experts with hazmat licenses. Too many steps, too many tanks, too much unintended mutation.

Don't bubble me, bro!

One of these days I may try zinc chromating, though.

Here's an easy intro kit to consider:
