I have a built in microwave oven with a broken door open button (the hinge plastic was too thin by design). The plastic is somewhat pliable, waxy. There is no chasing arrow showing the plastic type, but it is marked ">ABS<". In the past I've tried "works on plastic" household glue, PVA glue, super glue and/or plastic epoxy with mixed or worse results. Is there anything that really works on ABS?
