Been about 8 years since I used it, I put 90 on a fiberglass shower I built, but haven't used it since then. I used epoxy as I wanted a water proof primer over the urethane primer I had used to fill with. I used the 90 because I was spraying the shower with Black Imron. Have used couple other brands since then, but only the, grayish green. Martin Senior, and Nason, think they only have the one color. Back 20 plus years ago when I first started out I think PPG only offered black, and gray.
