| I wasn't thinking right and I used copper antisieze on a couple of barrel nuts. How screwed am I? |

Permatex suggests it to be used in applications where steel parts thread into aluminum. IIRC the point of anti-seize is to act as sacrificial anodes to prevent the parts seizing together. My guess if galvanic corrosion happens, it will be with the anti-seize, not the parts. |

Copper is more noble then aluminum. |
Liberals are a curious mix of communism and fascism, they want to destroy you but want to use your own money to do it.

A tube of Aeroshell 33 or 64 is like 20 bucks and will last you a lifetime. Or find a surplus can of molybdenum dissulfide grease and have enough for a couple lifetimes. Attached File |
