Those are not EPO rudders on my boat. I'm not sure what they are. The sticker on them said Florida Super Rudders. Wood core, fibreglass with a gell coat over the top. They were yellow, and kinda cruddy looking when I got the boat. I sanded them with a DA, and applied about 4 coats of Krylon plastic paint. It's starting to flake a bit, I don't know if its the paint, or improper surface prep.
