Technical Any Anti Rust Chassis Spray for Restored Car in Storage?

Unplated nuts, bolts and rotors: any thing to spray on them to stop rusting from humidity when in storage or parked during winter? (Also would like something that does not have to be removed. Spray and forget.)

Don't want to use any kind of Fluid Film, Surface Shield, WoolWax, TransStar, etc. which make everything oily, greasy, sticky, etc.

The only thing I know which is half decent (but not for rotors) is Original Armor All: soaking spray everywhere and let dry. (possibly use blow gun to blow out puddles, but that all) It actually dries with a little sheen and is not particularly sticky, etc.

Recently discovered Hyde's Serum Rustopper for rotors. It's funny because all the demonstrations of it show applying to the outboard surface - no care about inboard surface rusting. Sounds like a cosmetic product and not a serious on. Expensive but appears to be a tradition sodium nitrite aqueous solution (commonly used in machine shops, etc.) In this case, I'd just mix up a solution for cheap. It is not very effect, maybe 3 months worth so not a solution for chassis and suspension. OAA on rotors: wouldn't do it.

Back to Fluid Film for rotors: FF has a insane ability to creep - it will creep to the edge of sheet metal and continue to creep onto the back side! Now that level of oil, creeping oil, I don't think that would bother rotors and pads. But it might work on the car: once parked apply a miniscule amount so that it eventually creeps over the swept area. The rotor between the pads normally does not rust, so that creeping is not needed there.

There are anti rust papers that are used to wrap unplated steel parts (new rotors can have!) - don't know the chemistry - don't know if could adapt.

I'm sure someone has solved this problem. And as always, the H.A.M.B. is the ultimate place to look for difficult solutions.

Thanks

Gibbs oil, for sure. Spray or wipe on. Can be painted over later if need be (unlike or Armor All, which I believe is silicone based).

 

But what do those products do for the ability to stop safely?

 

Rust on brake rotors goes away when you use the brakes. I would never put anything like fluid film on brake rotors. You do not want to lube up friction devices.

 

I say move to where things don't rust in the winter

 

sounds like you want Bulldog Adhesion Promoter

Take a look at Cody Walls' post about it here: https://www.instagram.com/p/DJmIs55u2Qq/?hl=en

 

I second Gibbs. Good stuff. If you’re uncomfortable putting it on rotors, don’t.

 

Hard to argue with Cody Walls’ test. I’m going to try the Bulldog on some pieces.

 

Wow! I use the Boesheild T-9 at work. It works great, but now that I'm seeing Cody's test results I'll give give that Bulldog a try as well. Thx

 

Living 45 min East of Pittsburgh, how do you think I learned to do oxy-acetylene auto body sheet metal welding? (Yes, I worked 15 years in FL for P&W in Jupiter and there was no rust. Completely different reality but boring roads.)

 

This sounds like it could be the answer. Researching: what is it? Is it a coating like a primer or paint? Is it a hard coating? Is it glossy, semi or flat? Over time can it chip or peel since will be used on chassis/ suspension

It may not be a good choice for spaying down a complete suspension/steering/ chassis, but it might be good to selectively spray on unpainted nuts, control arm shafts, swaybar links, ball joints, etc.

Right now I soaked down some aluminum castings and shock towers in my daily driver with Original Armor All just to see how tackless it dries (it's been years since I've done this).

 

That is good to know!

 

Gibbs, stuff worked great on bare metal.

 

Does Gibbs become dry to the touch and does not attract dirt? (since people use on guns, sounds like it dries dry-to-the-touch.)

 

You need to wipe off the excess with a rag, but it doesn’t attract dust. I used it on my chassis after I sanded it down while waiting for the painter. It’s plenty humid around here. No rust, no complaints from the painter either. At least not about that !
