Yes. I am helping a friend restore his 56 Studebaker Power Hawk. Back then, no matter what color your car was, the inside of the trunk and the bottom of the decklid were a grey color very close to what I would call Battleship Grey. He found a source that said they had the correct color, but it was stupid expensive. He found a grey single stage acrylic urethane on the Summit site that looked perfect. I sprayed the trunk and the back of the decklid with my Iwata Super Nova 1.3 tip gun, and it went on like a dream. I was very impressed with it. Here are a few pictures.
