Was the top coat a sealer or base coat paint. On the base coat I would scuff with green scratchy pad on a sealer coat light sand. Myself after that much time I would be more prone to sand, apply a primer sealer and paint what the paint manufacture would recommend. It all really comes down to what you top coated with.
If you have a access to marine urethane they are bullet proof compared to car urethane's, but well worth it. Just make sure you use a good respirator, they can be lethal.
