At the convention, we ask Rick, who is a marine coatings expert, if he could put together a recommendation on a coating system for a typical steel hulled psub and he did.  Attached is his recommendation.  It is pretty much what Scott has done on Trustworthy.

Years ago I bought myself a sand blaster with the intention of doing this job myself. Very bad idea. It was a complete pain, especially recovering the sand to pass it back through, which required one to pass it through a sieve to remove any kind of foreign particles that would clog the nozzle. I had clogs pretty much all the time, sand everywhere, and ended up taking the sub off to have someone with proper facilities deal with it. I generally tight-fisted, but sand blasting is THE job I don't mind outsourcing.

Since I'm sure I will need to be recoating places where I'm doing thru hulls and such.  But my question is do I need to worry about the compatibility between the zinc coating and the epoxy that will on over the zinc ??   Should I put the zinc on the inside too ?   Are there different types of zinc coatings?
