I found that Duplicolor T282 Ford Dark Jewel Green (when Laid 2-3 coats over kelly green (any lighter brightish green) and then cleared is almost an EXACT match to the subaru green. You could spray it over that brighter green fender and it would match almost perfectly. If you wetsand/buff after it will match. (only difference in color is the flakes in the paint. Subaru has more of a bluish gold flake/ the can has more of a goldish flake...).
You can't tell unless you are 2 feet away. It will cost you $6 for a can and whatever clear you buy... So about 10-20 (with sandpaper) to paint it and fishish it. The matching paint might make it worth a little more. I can't believe this hasn't sold for $700 ... Heck I would have thought at $1000 it would sell. Wish I needed another car! I have always wanted a gc coupe.
