The board is finished. I'd just surf it and enjoy it for what it is. If the color bothered me that much I'd build and glass my own and sell this board to someone else.
Hello; I want to mention other points due to I deal with all that constantly (Yesterday was the last time...)
First; in defence of the glasser; botched work is one thing and other is a not so similar color work. One is technically done bad or with poor skills etc.
Other point is that some tints and pigments change when are mixed with the resin (also the glasser should be good at understand the increments of green added with the layers of fiberglass)
I ordered (bought) a champagne/caramel tint in a shop then when I mixed with the resin the color did not looked wrong, however, the final color was more on the tangerine side than on the caramel side. That board order did not specified any color (was for a surf shop) so no problem at all; but an example of a possible problem with some pigment brands.
Few weeks ago I ordered another caramel tint...but by phone call; when arrived the color did not looked caramel but more like to the maroon side of the spectre. It was in the need of yellow, but I did not have more...so I decided to mix with the resin and do the lamination; the result color was salmon. I really did not liked it; customer did not complained at all; 2 other people that passed by the workshop liked it! and want to order new boards with that color! Incredible. Then I told one of these guys that I preferred to not use that tint due to possible change in color etc but he was not liked that and di not put the order! He preferred the color than the functionality!!!
Also yesterday a gal asked to do another salmon color work...c mon.
Thanks for this perspective.-- gotta love it!
