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-F506)

  • Medium, gap filling consistency
  • 5-15 second cure time

Great for many uses! Especially on the edges of Tolex covering on your Amp that is trying to come off and all you need is to glue a little spot or two to make it look nice again. Here is a "Black Tolex" Tip for you! If you want your old amp to shine again like it did when it was NEW use "tire black" on it. Don't spray it directly on the Tolex. Spray it on a cloth and rub it over the Tolex evenly. Wait a few minutes and wipe off the excess. Give it several hours to dry! If you want it a little shinier, apply a second coat in the same fashion. Don't over do it! Two coats should bring back the original luster of the Tolex. Just make sure your amp surface is clean before applying the tire black. It will look like a new amp. Be careful not to get any on the grill cloth! Most Amps have Silver or some other light colored grill cloth. The results are amazing!
