I have a 1998 Nacra I-18 that needed some love. I had excellent luck with VC Performance Epoxy/Paint (2 part). You use the paint/tip method and with some patience it comes out pretty smooth. You can sand with 500 and then 1500 wet/dry, then buff with power buffer and rubbing compound.

I ended up painting about 4 coats on the bottom taped off (about 6-8 inches wide) then painted 2 coats to the mid line of the hulls (again using painters tape). This did leave a "ridge" and the paint is way whiter than 10 y/o hulls so I added a vinyl stripe (inspired by blue painters tape). I may coat the whole boat with another coat or 2 to make the boat effectively new this spring.
The original sacrificial layer is holding up nicely after 3 seasons. We beach our boats on every launch/recovery as we have nice sand and my boat sails ... well.. a lot.
