Andy,
It depends on what you are going to do with the boat, dry sail or wet
sail. Since you are taking off the old bottom paint I would assume
dry sail. If that is the case then I would suggest a two part epoxy
paint. I did this to Exocet by just rolling it on with a sponge type
roller. Then I spent many, many hours with a long board getting it
smooth as glass. Then buff it out and it will last a long time.
If you are wet sailing it then you will probably want something much
better for anti-fouling. I believe "Light n Up" used some new
technology stuff on their bottom last year. Depending on were you
live (i.e.- not in California) then you can probably have a lot more
options. I forget the name of what they used but hopefully they will
chime in.
I had the graphite stuff on the bottom of Opus when I first bought
her and when wet sanded smooth it worked just fine for dry sailing.
Hope this helps.
