Since returning i've been trying to get off some less than steller paint jobs from 20 years ago. I've had great results using dettol and it doesn't touch the plastic. However it appears that someone seems to have been a little libral

with the gule on some models so i was wondering if anyone new how to remove glue from plastics or part plastics.
I'm not sure if it's superglue or plastic cement.
Any help would be nice. thanks in advance.
