Here's the process I would recommend - it worked for me and the paint still looks good on that boat a year later (I don't have it anymore, but see it every tournament we have since a guy in my club bought it).
1 - sand it down with a wire wheel from walmart (goes in your regular drill - get 2.. like $5 each)
2 - let it dry and wetsand it with 300 grit sandpaper at night (if you paint during the day).. if you paint at night, you'll probably have to wait til next morning
3 - put a light coat of paint on - multiple light coats will last much longer than 1 big one... and the finish will be better too. Let the first coat of paint dry completely (maybe 5-6 hours depending on your location and the temperature).. wetsand it again and then put a light 2nd coat on (little thicker than the 1st). When it's tacky and not shiny-sticky, put on the 3rd coat a little lighter than the 2nd coat. When the 3rd coat is completely dry (maybe 24-48 hours because that 2nd coat has got to dry too), you can lightly wetsand it again to take out any blemishes if there are any with the paint (runs, drops, etc.)
Now if you're brushing it on, it's a completely different story, but still the same process. Either way you do it I suggest getting a medium reducer (available at parts stores that sell auto paint). Mix it at a paint to reducer ratio of 5 paint to 1 reducer (get a mixing cup at the parts store too, it will come in handy). The reducer will make your paint go a lot farther, and if you have some paint left over after the 3rd coat, put another coat on the bottom - you'll be glad you did!
