Listen to BOB VILA ON METAL ADHESIVES or read the text below:
Adhesives offer several advantages. Unlike bonding methods that use heat, adhesive don’t cause metals to distort. And since there’s no heat involved, you can use an adhesive to join different pieces of metal, each with different melting points. There are a couple more positives too: Adhesives generally don’t cause discoloration, and you don’t have to pre-drill holes for fasteners.
Adhesives do have some drawbacks, however. There’s usually a bit of surface prep involved and once applied, adhesives may take quite a while before they cure to full strength. When the bond has fully cured, though, you won’t want the job of detaching the two pieces—that could be a major undertaking!
