Abstract: An apparatus for applying a finish coating of a liquid epoxy containing metallic flakes to the cylindrical exterior surface of tubes such as drawn aluminum tubes. The apparatus includes a carousel which supports six tubes spaced around the periphery thereof with the carousel being rotated about a horizontal axis. A rotable rubber liquid coating applying roll is located below the carousel but offset from directly beneath the rotational axis of the carousel. The liquid epoxy coating is applied to the rubber roll above a metering roll. The carousel is rotated about its horizontal axis to move the tubes into and out of peripheral contact with the liquid coating applying roll, with each tube remaining in contact with the roll through an arc of appoximately 10.degree. of rotation of the carousel. A gear drive rotates each tube while in contact with the liquid coating applying roll in such a manner that the tubes and the liquid coating applying roll move in the same direction and at the same surface speed.
