It's not a solution as it has two distinct phases. That's what gives grease its low shear viscosity compared to fats and jellies.
Quite which of the phases is continuous I do not know.

I were wrong about those bolts

@IWRATS, so are you trying to say copaslip won't accelerate galvanic corrosion?
I have a big tub of the stuff in the garage BTW, but I only use it on alloy/alloy or steel/steel connections. If it's alloy/steel I use plain old axle grease, that brown gooey stuff. Works a treat.

@crowriver
I'm saying that I can't see any plausible mechanism by which it would accelerate bimetallic corrosion and that I have no concern about using it in this application.
Water, air and salt are the enemies of ferrous metals, colloidal copper is but a bystander.

So I did a bad thing to my front brake too. It's like I have become IWRATS Destroyer of Bicycles.
The fork lowers are magnesium and very soft. The lower bolt hauled and stripped the female thread, which I repaired with a Helicoil insert. I knew the upper one would go too, it did and I Helicoiled that too. Except the male thread on the bolt kept stripping. Close inspection revealed the cause - sheer carelessness on my part.
I'd accidentally swapped the bespoke Helicoil tap and the standard M8 tap in my tool boxes. The Helicoil tap is M7 point something. I'd tapped the hole too big. Drat. Rats.
What to do? Ah yes. Use epoxy resin to weld an M8 brass bolt into the M8 tapped hole;
Saw the top off flush and mark up with the bolt position;
Drill a 4.5 mm hole into the brass bolt and tap that to M6;
I'm still not sure if the shame at borking it in the first place is overcome by the pride of bodging it back into life.

This is taking bodging into another dimension! (What is the correct term for a bodge with 2 distinct phases?)

@kaputnik
I cannot answer your question, but many thanks for not mentioning tri-metalic corrosion.
I did enjoy my precise, confident Helicoil work being the source of a luminous waterfall of shame.

A Bodge Too Far?
(Dah dah di dum dum, dah dah di dum dum, dee dee dit dah di dah di dum dum;
Dah dah di dum dum, dah dah di dum dum, dee dee dit dah dee di dummm...)Magnesium, epoxy resin, brass, aluminium or steel bolt? It's like scratch building scale model steam engines or something.
Well bodged I suppose ( steady hand needed on the drilling!) but at some point probs just get new forks?

at some point probs just get new forks?
I'm a bit of a hippy. Repair things until they can't be repaired and then replace them.
These are the third forks to have gone on this frame in its seventeen years of service. I expect them to last another four or five years. I'll replace all the seals this autumn some time.
I started drilling the hole by twirling a 1mm drill between finger and thumb for maximum precision....

As shown this was no bodge. It is a properly thought out repair second to only a new factory drilled frame

I am quite disarmed. Thank you.

My seat bolt snapped again this time on my way back from Ardrossan harbour near Beith on the way to Paisley . I noticed a Saltire flying behind the wall on the other side of the road, there was a house on a small backroad with an ornamental bike in the garden and SNP on the roof. I knocked on a door to ask what way is the nearest station as my phone was flat. The person I asked had a workshop in their garage working on old motor cycles and another old bicycle. He made me a seat bolt out of cutting and grinding a car/motorcycle long bolt and gave me ½ inch wrench to adjust it with. My Halfords bolt lasted 7 weeks, but it may not have been the bolt as the helpful person advised my seat post groves looked warn down. All he asked was that I vote SNP.

I believe that the separatist in question may have been flirting with Section 113(2) of the Representation of the People Act (1983) there, but hey-ho you got your bike fixed.
PS My brake post survived moderately severe wilderness usage yesterday.

Beth also very close to my childhood stomping ground. My granny used to make wardrobes there and occasionally took us to the George picture house. Not often in case we became too attached to her.
We did go to Beith Fair every year, it rained.
Speedway, Walters, candy floss.
There is a song I can sing on PY night out about Beith, kilbirnie and lochwinnoch.
