Check out different Locktite products. Some are OK with plastic. We used
to use the weld sealant for mounting ballbearings in a check sorter.
Worked
better than some of the other locking compounds.

I agree, that you have to be diligent when looking at products today to make
sure they work with plastics, fiberglass and other composites.

I spent a full day calling local marine repair places when I was upgrading
LCDs on my aluminum bass boat and wanted to be DARN sure the sealant I was
looking at was ok for metal hulls and not just fiberglass. All turned out
ok, but I've had experiences similar to yours and am very cautious everytime
out now as a result.

My question would be did it really weaken the plastic or did you use too
strong a compound and the plastic just gave up the ghost as you tried to
remove them. If they broke easily then I agree, the chemicals in the LT
likely adversely affected the plastic. If not, just look for a weaker
compound next time as they make varying levels of it.

Just out of curiousity, what color compund did you use? Hopefully not red or
blue (IIRC) as I think they'd be too much. Do they still make the weaker but
still effective green compound? (Hoping the color references are correct, I
never can keep all the Lock Tite colors/strengths straight in the noodle)
