Gretsch Syncromatic – Masking of the binding channel

The finish used to glue in the binding is a solvent based glue which melts the binding while adhering to the wood.  The solvent will also eat the finish on the guitar so it is necessary to mask off the binding channel.  The finish on this guitar is very delicate and would easily be pulled off with aggressive tape so I used the tiniest strips of delicate painters masking tape that I thought I could get away with.  Before applying the tape I weakened the adhesive further by sticking it to the fabric of my shirt a few times.  With careful peeling this should not harm the finish.
