I have a 1979 Stratocaster that was originally a 3-tone Sunburst Ash body. A previous owner had it refinished in black over the original finish, but did a purple-ish sunburst in the back. It's actually kind of cool, but I eventually would like to refinish it in all-black or in an authentic late '70s 3-Tone Sunburst finish. To whom or where should I consider sending it to get the most authentic 3TS refinish job? Thanks!
