Osmosis treatment: Epoxy resin or barrier paint?

There are a lot of epoxy products on the market especially marketed for osmosis treatment and for protection against it.

The question is: Is a epoxy resin a better option to use than a epoxy barrier coat product (often colored/paint?). Or, are there any additives in those products formula making it better against moisture?

Interlux 2000 beats neat epoxy hands down. It's the micro plate technology. I speak from a large case sample, not just a few boats. Sea Hawk Tuff Stuff is trying, but it's not quite there yet. The rep would be pissed to hear me say it, but he knows it's true...

I agree with Minaret. Epoxy resin is slightly porous. To protect your gel coat from blisters you would have to put on a very thick layer. Interlux 2000 has small flakes of waterproof material (Mica?) mixed in. The flakes won't allow water to travel directly through the epoxy carrier. The effect is that you need far fewer coats to prevent the water from migrating through to your gel coat. It is also a good primer for your antifouling paint to bond to.

Even with West System Epoxy barrier coating you'll add aluminum power for more plating and moisture protection and graphite powder for a harder coating and apply to 40 to 60 mils, about .040 thousands thick.
Then your going to have to sand, to get the bottom paint to stick.
Interlux is going to save that step, as well can be applied in successive coats, without sanding in between.
