if i wanted to bond a new metal tab or whatever to a plastic box, I'd
use Marine Tex...
about the best two-part epoxy I've ever found.

  Hardware stores and marine supply places.
this one..

comes in white or grey .

plastics are 'funny' of course ...but for regular hard black plastic
..this stuff bonds quite well.
