Need help on headlight repair

This is my first time opening up the headlights to do a blackout and retro and I was almost done without breaking anything and then I chipped the edge of the lense housing. Any suggestions on how to fix this? I thought about glueing the chip back and painting the trim black. Also do you guys strip out all the sealer or just add new sealer on top?

 

Use the epoxy that cures with ultra violet light and try to strip out all of the old sealer before you put it back together for a leak free seal.

That UV plastic type stuff may work, but in my experience it isn't too strong. In your case you might just want to use super glue gel. I used that UV epoxy stuff to add a tab to my fog lights though since my bumper was a little messed up at the mounting spots and it works fine. It says right on the package it doesn't behave like an adhesive though.
