Blue thread lock, Not so removable

[rpaloalto]

So I'm having a hard time removing a LarryDFW brass lens. That I mounted with some blue Loctite.
One of my lasers required that the lens be backed out a few turns in the aixiz thumb grip. So I used some removable loctite. The blue stuff not the red.

I now want to try this lens on a different laser but the thumb grip wont budge.
This thing is on their good. I have all but striped it trying to use pliers warped in clothe.

I tried soaking it in isopropyl alcohol, still nothing.
I read that acetone can help, but fear this may damage the coating on the lens or dissolve the set glue for the lens.

Any ideas

Nevermind,
I just heated it up with a small torch to loosen it.
I guess I used to much thread lock.
