Jazz, Thanks for the info! From what you've said, I've made a few mistakes. Now I have to double check my Honda trailer hitch.

Thanks Chris - good scoop !!! I've always used the silver (gray) stuff on everything. Now, I'll go buy the copper stuff. FYI - For the exhaust manifold, Alfa used brass bolts & I never had any problem removing them even with no lubricant. I did replace rusted studs periodically.

i use loctite Graphite-50 for spark plugs.

Back from the deep...

Rock n Roll is great stuff too. I have put it on bolts that have come apart easily despite years outdoors. Works well in the wet as well as high heat applications.

For consideration:

Loctite LB 8036: https://www.henkel-adhesives.com/us/...e_lb_8036.html

Based on their documentation, it is suitable for:
Alloy
Copper
Iron
Steel
Stainless Steel

Kind of a one-size-fits all anti-seize.

Holy thread resurrection!
I don't see aluminum mentioned - they mention "alloy" but not aluminum alloy.

[Shifted]

A lot of what we call aluminum is actually an alloy. Like "aluminum" wheels. But, I agree, "alloy" is ambiguous in their description. Since they separately call out steel, which is technically an alloy, do they mean aluminum alloy? Probably not.

In the TDS it says that the chemical type is "aluminum complex". Which is interesting considering that they say the product is "non-metallic". An aluminum complex is usually used as a thickening agent, including in grease for steel bearings.

But, this page says that the primary additive is graphite: https://www.grainger.com/category/lu...&filters=attrs

And this one says Aluminum: https://www.mcmaster.com/1821A41/

Clear as mud, right? Grainger is probably wrong.

The TDS also says that it prevents galvanic corrosion, which implies it is safe for use with dissimilar metals, like a steel fastener installed in an aluminum case.

Either way, it should be safe for use with aluminum and aluminum alloy.

The bottom line is that I've been using it as my go to anti-seize for a couple of years, including on aluminum threads, with zero issues on disassembly of any material types or combination of material types.

This is an interesting read on the topic, albeit from another competing manufacturer: https://www.antiseize.com/PDFs/how-t...-antiseize.pdf

They mention moly anti-seize, which seems like it is compatible with almost all materials.

This is Loctite's version: https://www.rshughes.com/p/Loctite-L.../079340_51048/

And Dupont's version: https://www.dupont.com/products/moly...000-paste.html

Specifically safe for:
-Aluminum
-Brass
-Carbide
-Copper
-Iron
-Nickel
-Stainless Steel
-Steel
-Titanium

I've been using a lesser version of the Molykote to aid in assembly of some components and it works really well.

I think I'll give the moly anti-seize stuff a try. Looks really good.


My original point, though, was that there are some pretty good anti-seize options out there beyond what was available 10+ years ago. The non-metallic stuff is great and covers a lot of bases. And it looks like the moly stuff is even better. Having one product that I can use for all things is ideal for me.
