Fixes finish chips fast! #20-X is our medium-viscosity clear instant adhesive in a special slow-curing brush-on version. It's remarkably handy for touching up minor dings in guitar finishes—much faster than waiting for drop-filled lacquer to dry. It flows smoothly, the brush/cap gives you fine control for filling chips in the finish, and the bond is nearly as strong as our other super glues. 1-ounce bottle. Important: The brush is designed only for this formulation, with special polyethylene bristles that resist hardening. Super Glue Accelerator should NOT be used. To help prolong shelf life, store super glues in a cool dry place. Warning! Bonds skin and eyes instantly. Use in a well ventilated area. Keep out of the reach of children.
