I have made three piers and have painted everyone of them with rubber undercoat for cars. It is paint-able over the top if you would like a different color but I found I liked the black semi gloss. The rubber also took some of the ring out of the pier and protected eye pieces from bumps and bruises. I have had no problems with rust or peeling, just make sure you dry it under heavy infrared lights to help it cure faster. Check the photo section for my last pier.
