S-F500XAdhesive - Bob Smith Industries, Insta-Cure Super Thin Cyanoacrylate
Multiple Options Available
Bob Smith Industries™ Insta-Cure™ Super Thin Cyanoacrylate. A must have for luthiers!

Insta-Cure™ has a water-thin viscosity that wicks deep into joints by capillary action and cures in a matter of a few seconds (1-3 sec.). Surfaces to be bonded must be tight fitting (no visible gaps) and should be held together or clamped while you apply the CA around the edges of the seam.

For glue applications with small gaps or looser fitting joints the higher viscosity Insta-Cure+™ is recommended.

  • Water-thin consistency
  • 1-3 second cure time
  • For tight fitting applications
  • Available in 1oz. and 2oz. sizes


WARNING: These products are eye and respiratory irritants. Product can bond skin instantly. Keep away from children!

S-F502XAdhesive - Bob Smith Industries, Insta-Cure + Gap Filling Cyanoacrylate
Multiple Options Available

Bob Smith Industries™ Insta-Cure+™ Medium Gap Filling Cyanoacrylate. A must have for luthiers! Insta-Cure+™ is a higher viscosity CA for loose fitting joints in which the adhesive must bridge gaps or the parts to be glued don’t fit perfectly. Medium viscosity super glue is the most common glue used in many luthiery applications due to it’s cure time and viscosity. Recommended for binding repair and small poly finish touch ups. Normally, the thicker CA is applied to one surface and then the parts are held tightly together for about 5 to 15 seconds. For large surface areas, including those with close fitting joints such as laminations, INSTA-CURE+ ™ should also be used. To prevent premature curing, don’t spread the glue into a thin film. Lay down a serpentine bead with about 1" separations on one surface, then assemble the parts, letting the pressure spread the CA out. To speed up curing time use the Insta-Set accelerator!

S-F506XAdhesive - Bob Smith Industries, Insta-Set Foam, Pump Spray
Multiple Options Available

Bob Smith Industries INSTA-SET™ CA (super glue) Accelerator. INSTA-SET™ is a catalyst which acts as an accelerator that allows CAs to quickly cure in thick layers by enhancing the alkaline conditions during polymerization. INSTA-SET™ in a spray bottle is normally used to cure the CA that flows from joints when parts are pressed together. Applying an additional bead of thick CA along a seam and then curing it with INSTA-SET™ significantly enhances a joint’s strength. For difficult to bond materials, INSTA-SET™ can be applied to one surface and CA to the opposite surface. When brought together, they will bond instantly. INSTA-SET™ is formulated with a strawberry scent and activates CA in 6 to 8 seconds without any degrading of the CAs strength, which can occur with many other accelerators. It is compatible with all surfaces, even clear plastic and white foam.



  • Convenient pump spray (2oz.
