try alcohol first for solvent, it should not mangle coil forms. if that
doesn't work, a paintbrush with a little bit of acetone is the next step
for solvent.


What I did for those stubborn slugs was to heat them with the tip of my
weller. The heat will soften the paint/sealant and not damage the coil
form.

Usually a drop of solvent will loosen them. If the coil
forms are plastic it might be a problem, but you can test the
solvent on the end of the form first.

tin-socketed chips, you understand, and the machine was well enough
built so you could get away with it.

But the skill is in where and how hard to hit it ;-)

Worked with a piece of production equipment I dealt with, with a relay
which stuck occasionally, no matter how many times it was replaced
(Note: never buy serial # 0001 of anything).

It was far simpler to kick it in just the right spot.
