DIY Barrier Coat

I am thinking about doing an epoxy barrier coat on an 1986 Tashiba 40 as a preventative measure before taking her to warm tropical waters. Can anyone point me to informative websites about the process (something like a "how to")? What is the best way to remove years of old bottom paint: soda blast, scraper, sanding, chemicals? Once the bottom paint is removed, is the gelcoat removed to the laminate? Or will a sanding of the gelcoat provide enough adhesion for the epoxy to bond? What type of epoxy is used: will thickened West epoxy work, or are their special epoxy barrier coat products? How is it applied? Will the epoxy self-level or will fairing be required? I'm a fairly handy DIY-er, but is this a job thats better left to a professional?
