I have alot of information on this process. In the past 2 years I have done it to both a Hobie 14 and 16. I'd suggest filling in any chips or scratches with a fairing compound then spot prime the areas that you faired. The next step is to sand the hulls smooth down to about 220 grit. I used an Interlux one part product called Toplac that is very easy to apply and does not require priming unless the surface is in bad condition. I applied the paint with a foam roller them used a brush to brush out the streaks and bubbles. The can says you can apply 2 or 3 coats within 24 hours. I found that in order to get a good finish I waited 24 hours after the first coat, sanded the drips then applied the 2nd coat. It took me 1.5 quarts to apply 2 coats to a Hobie 16 hulls only (no decks). See htttp://www.yachtpaint.com for more information or feel free to either PM me or e-mail me.
