Corrosion prevention on exposed threads

[buck91]

Wondering what the best corrosion protection on some exposed threads would be? I guess the two competing concepts I have would be either spraying them with Amsoil HDMP or spraying them with some rust oleum spray paint. I guess we could look at fluid film, Grease, or other things but I feel like the two listed above are the best choices.

Location might factor in.
I wish "rubbery, friction fit things" were available. A smear of grease and on they'd go.

I shoot all my suspension component threads with Krown but any of the under car corrosion inhibitors would work well.

I use AMSOIL HDMP for all of my exposed threads on the underside of my cars. Works wonders and last several years under a car.

I just did a suspension job on my wife’s 11 year old Subaru (only 2 applications of AMSOIL HDMP over the 11 years). Everything came apart easily without the need for penetrating oil. I did the same job on a colleague’s 10 year old Subaru that did not benefit from the AMSOIL HDMP, everything was much more difficult and we snapped the head off of one knuckle bolt.

They’re pretty cheap, pack of 100 that’ll cover 1/4-5/16” up to 1” long is $6.05.

I've seen similar things at the big swap meets, such as Carlisle.

I had my TR steam cleaned for Waxoyl, and just went through covering any exposed threads with Boeshield. Prior to that, most were protected by the on-board rust prevention system; copious oil leaks.

I use a copper electrical corrosion paste. Get it in your clothes and it won't come out but whatever part I put it on it's still there when I look again. great for disc brake pins.

Corrosion X, "Max Wax" is a CiC that is about the best there is. It forms a waxy coating, hence the name. It will hold up remarkably well. It puts Boeshield to shame in real world applications.

Woolwax or fluid films

 

[Yah-Tah-Hey]

I use Eastwood aerosol corrosion inhibitor. I have some fasteners under my Camry that I coated with the wax like material in 2004 still in place. Not the perfect solution but works for me. Comes in amber and black.

It depends upon how much spray it is exposed to.

Cold zinc spray, grease, paint, wax spray, lanolin, or some combo.

A lot. These will be fuel tank skid plate bolts on a daily driver in the salt belt. I’ve decided to lightly paint them with rust oleum prior to install and then spray them with HDMP after install.

Yeah that’s a good option. I’d also consider cold zinc spray.

HDMP works great.

This! T9 Boeshield dries to a thin, waxy layer.

Kano labs weatherproof, unless they discontinued or changed it.

Tractor hydraulic fluid gets pretty hot too.

Since you mention threads specifically... I'll throw out a different thing... Vibra-Tite Threadmate. It coats the threads with a re-usable (a few times, anyway) coating that is intended to reduce backing out (like Loctite). I've found it to be a good rust and corrosion preventative, as well.
