Part 3: PRS-Style Binding
After an hour remove the latex tape.
Using your index finger as a depth guide . . .
. . . sand the stain off the top edge to create the top of the "binding".
A sanding stick, with 150-grit does a good job of exposing the edge also and gently rounding it.
Though the sanding created an almost-perfect top edge, I used a single edge razor blade with a scrap of binding taped to it as a depth stop . . .
. . . and removed any blue stain that the sandpaper didn't get—this also creates a very clean line between blue and clean maple.
Let the guitar dry overnight before spraying any lacquer.
This guitar is now ready for Part 4: Sealer and scuff sand.
