If you are able to gently separate the parts and can force in some high quality premiun construction adhesive the bond would be very good. It is not black, but it could probably be painted. I've used it for lots of things and it sticks better than silicone (if surfaces are clean) but it is not as flexible. I recommend that you do your own test on some scrap parts because it's a LOT harder to remove than silicone if you aren't happy with the results.
