The coarseness of sandpaper, designated by a numerical value, is a crucial factor when stripping a guitar’s finish. This number, often referred to as “grit,” directly correlates to the abrasive power of the sandpaper. Lower numbers indicate coarser abrasives, suitable for aggressive material removal, while higher numbers signify finer abrasives, intended for smoothing and polishing.
Selecting the appropriate level of coarseness is paramount to avoid damaging the underlying wood. A grit that is too coarse can gouge or scratch the guitar’s body, necessitating extensive repairs. Conversely, a grit that is too fine may prove ineffective, prolonging the stripping process and requiring excessive effort. Historical methods often involved harsh chemical strippers, but modern techniques prioritize controlled, progressive abrasion for optimal results.
