The fretboard was applied by silkscreening, over the paint coat of laquer, and the laquer has much checking under the silksreening ...with small cracks along most of the checking. After carefully cleaning the fretboard, I will mask around it and then seal it with as many coats of thinned clear polyurethane as required to reach down into and fill and stabilize the checking in both the base coat and in the fretboard silkscreening. Once the checking is filled then successive coats of clear polyurethane will be added to level the checking and provide an excellent, protective, non-glare satin coating over the fretboard. I will then run a razor knife along the masked edges before removing the masking tape; And that will separate the body checking from checking under and on the fretboard so that pulling the masking tape off will only lift the old badly checked topcoat on the body and not the fretboard. After the urethane cures for about 10 days then the fretboard can be masked off for removal of the body's finish for whatever new finish or natural treatment might be desired. |
