The white screen gasket (trim) on my MacBook A1342 is peeling off. How do I insert it back? It keeps peeling back off even when I insert it back. It only happens at one specific spot. I don’t want to replace the trim. I just want to glue it back in. What kind of glue-adhesive may I use?
Don’t use standard super glue; it will discolor the plastic and won’t have a strong hold. Loctite has a special cyanoacrylate formulated for plastic. Look up “Loctite 681925” for details. To do this RIGHT you’ll want to disassemble the screen so that the gasket sits properly behind the glass. You could try fudging it by just pushing it back into place, but then you’re going to be pushing the adhesive out of where it needs to be.
