BSI Black Rubber Toughened CA Glue
This is a rubber-toughened cyanoacrylate that forms superior shock resistant bonds on non-porous surfaces. The black colored CA has added flexibility for the bonding of metals, fiberglass, rubber, carbon-fiber and other advanced materials. Setup time is 20-40 seconds, which can be accelerated with INSTA-SET™. When cured, it's pliable enough to be carved with a hobby knife.
This is an excellent ca glue to fill in small knots and cracks in wood pieces. Sands off easily and even with the wood.
