Sand and buff. Next, lightly sand the glue-covered area with 600 grit paper to feather it to the edge of the fretboard or binding (Photo 4). Now gently sand it with 1500 grit paper to smooth out any scratch marks.
Finish this job using extra-fine buffing compound and a polishing cloth (Photo 5). I use Planet Waves Restore for this last stage, but you can find other buffing compounds at auto stores or online.
Now step back and admire your work, which should look similar to Photo 6.
After flipping the guitar over on its opposite side, position and secure it (remember to keep the neck perfectly level), and then repeat the process for the other end of the nut.
And that’s it—another task completed, thanks to super glue.
