Please forgive me if this is in the wrong forum or section.
Ive had an inert cts mini that ive been wanting to replace the head on due to the lip that the safety lever sits on has somehow chipped off.
Upon trying to unscrew the head i noticed it wasnt budging what so ever. I contacted the seller asking him if the threads were loctited and he said no its just corrosion buildup and to let some liquid wrench soak into the threads for ease of removal. So far thats had no effect.
Was checking to see if anyone would potentially have an alternative solution to removing the head.
I know its an oddly specific question but I figured id check here just in case!
Thanks!

Fuze body in a vise with non-marring jaws and a big strap wrench on the body.

Seems to work for me but I've only taken maybe ten apart.

Thanks! I will try this and report back. Do you use any solvents along with it?

Soap and water. They seemed more gummed together than anything else to me.
