Back in the old days, around 1980, I painted the sterns on my Nacra 5.2. I went to K-Mart and bought a can of the cheapest, flat black paint I could find for $1.19. Painted both sterns --- looked great until it was sold in 1984. Did the same thing again on an old 5.2 my brother bought in 1999. Same results. From my experience, I certainly wouldn't go overboard with the paint selection.

Just my 2 cents.
