Here's a link to a guide booklet for using Interlux's Interprotect product, which is what most people use. A search on Sailnet produces quite a few threads with reference to barrier coats but it would take some reading to find the gems you might want.

In our experience, application is simple, preparation must be complete, and the more coats the better as far as longevity and secure protection goes. (We did 6 - 8 coats on our last boat)

If you search back a little over two years ago, many were using epoxy to coat the bottom of their boats with a barrier coating. Then a non name brand epoxy manufacture started to say on their web site that epoxy paint was better then epoxy resin as a barrier coat and many have jumped on his band wagon. I have not and have used epoxy resin on my boat and I will ask if you have ever tried to sand epoxy resin off of something and if you have tried to sand epoxy paint again off of something. Enough said?
