Bonding Smooth Surfaces using Cyanoacrylate Glue or Super Glue

HOW CAN I BOND SURFACES THAT HAVE TROUBLE BONDING?
Objects that have smooth surfaces typically have lower surface energy and as a result, users experience a more difficult time getting them to bond. A few examples of material with low surface energy are smooth & "finished" glass, metal, and plastics.
When bonding these types of surfaces, it's recommended to roughen up the surfaces to-be-bonded with an abrasive (e.g. sandpaper). This will add more surface energy to the material which allows the CA glue to better stick to the surface.
