Dont use a acrylic enamel because for just a few dollars you more can get a acrylic urethane which will much more durable.
My favorite cheap single stage acrylic urethane is PPG's Omni MTK. Painted tons of skis with it and it has lasted. It doesnt chip or fade, even in this brutal AZ sun.
PPG also makes Omni Plus which is a base/clear system and its still pretty cheap.

Also as mentioned Dupont "Imron" is a good ol paint too. The 1990 purple/yellow SN SJ in the pics below I painted with Imron in 1992 and the hull sits in my backyard now and the paint still looks awesome!
