    At risk of repeating myself……

    Just buy some ceramic anti seize, it doesn’t suffer from galvanic weirdness, it can magically fill fairly large voids/threads, is heat resistant, is cheap because it’s for automotive use rather than cycling is the new golf charge 10x more for a tiny little tube and best of all the description uses the term nano.

    Anything that isn’t branded as cycle specific. So a scoop from the tubs of grease kicking around the shed. Kept me going for 45 years and I suspect bikes in general for another century on top of that.

    I wouldn’t say there is a huge difference in cost bike vs car non-copper anti-seize.

    e.g. the Shimano stuff is pretty reasonable at £20 for a 455g tub with a brush in the lid (which makes it very convenient to use) and 100g tubes of various bike or car stuff is generally £5-10.

    For those saying there is no galvanic issue, Molyslip (makers of Copaslip) specifically make Alumslip to avoid using copper in joints involving aluminium and steel. In practice you won’t see a seizing problem as the galvanic issue eats the aluminium……

    Slightly different circumstances, but here is my steerer starting to get galvanically eaten in 2-3 years  due to the presence of steel, aluminium, water and copper.

    I don’t think that anyone is saying that. IME of both steel and aluminium frames, with components in a variety of materials, copper grease doesn’t cause a noticeable problem. I don’t own a carbon frame so can’t comment on that

    I’m all for a one-pot solution. When my 1.1lb (500 new-fangled grams) tub of copper grease runs out then I’ll buy ceramic, as recommended by RNP ^^

    IME, no visible damage to threads, etc. Just clean the old copper grease out and replace once or twice a year

    The key ingredient here is water, which is the electrolyte that allowed galvanic corrosion to take place. Grease will keep it out

    I am a liberal user of copaslip and have never seen galvanic corrosion.  I use grease on stuff that is taken out often, copaslip on stuff that is dismantled rarely and locktite very occasionally on critical bolts.  Many times I thank the great god copaslip when  for example a disc bolt comes out nice and easily
