Apply a mixture of epoxy resin A and B to all areas where the adhesive has hardened.

Fill all the gaps with putty. You can sand it down later, but push it in with your fingers so that it is as thin as possible.

As with cleaning the glue, after applying the putty, remove the putty that has come out with a cotton swab moistened with ethanol.

Allow to dry thoroughly for at least 30 minutes.
