Have you had a look at the MCW Finishes web-site? They have the Gulf livery colors there. I've always liked the Mr. Color paints as well, but hadn't tried any of their gloss colors on a car, so they may be good as well. Tried many of the MCW paints recently on my first car build in years, and I have to say that I'm really impressed with the finish they produce. The colors have been very accurate as well. Just an alternative option if the Mr. Color doesn't work out, and their enamel thins nicely with Mr. Color Leveling Thinner.
