Golden Hermetite

I used the above when renewing my engine anode on the plug threads as it is supposed to be non-setting.
It appears to have set! Despite applying considerable torque........ socket extension onto the head of the plug and 18" spanner it won't budge.
Gentle option seems to be to apply a solvent into the threads to try and break it's grip............ any suggestions?

Sounds like the ideal stuff. ~~ "Easy dismantling"

The main solvent seems to be methylene chloride (methylene dichloride, or dichloromethane)

A paint stripper based on that perhaps eg Nitromors All Purpose Paint & Varnish Remover but i would not hold out much hope.

Tried it while hot? How about a freezing spray directed at the anode? (The stuff plumbers use for freezing pipes)

Centre punch the stub then drill the remains out Eventually it will spin out.

Thanks for the info.

Think I may try a combination of the two........... try the paint stripper to remove as much as possible then give it the ice treatment when I try to move it.

Sounds like a last resort but thanks for the reply.
