MAS has a paper on their website about barrier coating (or at least they did back then) and I followed that process. I also called and talked to them with some other questions I had at the time. They are quite helpful.
The first coat is their regular, "thin" if you will, resin. The other coats are the thicker Flag resin. That was how they said to do it. I put 6 coats on in all (2 more than they recommended at the time -- don't ask me why I did the 2 extra ones. I just did.) If you put on the next coat within X number of hours, you don't have to sand it. Sorry -- I can't recall the timing on that. You can recoat as soon as it hardens enough that your thumb can just dent the last coat. By applying the coats that close together they chemically bond and effectively become one thick coat.
One thing I called them about was whether to go ahead and add the WEST barrier coat particles to their
epoxy. WEST makes a big deal about that additive making the barrier coat stronger. The MAS guys said to forget it, that the
epoxy is plenty strong enough by itself not to need any additive.
As Jeff says, the MAS
epoxy always was lower blush than the WEST (another reason I went with it) but now they have come out with a formula that I think eliminates the blush all together -- or at least reduces it considerably.
As for Dawg's comment about the Interlux 2000, yes that is a good product to. It's very much a personal preference thing. I don't think either one out performs the other. I went with the MAS
epoxy because I had worked with before and liked it.
