Hi All,
I'm doing a complete bottom job and replacing the cutlass all in one wallet punching motion.
Her hull has been sandblasted and is drying out over the winter in anticipation for an epoxy barrier coat and bottom paint in the spring. I just need to decide how many coats of epoxy I need (or can afford) to provide protection.
I think West suggests two coats and I've heard that three is the way to go. It's about a $350 difference so I like to ask the forum for their thoughts or suggestions.

If you are using Interprotect Barrier coat then go with the recommended number of coats and you can't go wrong. No experience with plain epoxy for this.
We had the bottom blasted in 2002 and the Barrier coat done by a professional in Deale, MD. They recommended and we went with the Interlux product.

There is no good opinion other than the manufacturer's for their product. Choose a system and go with what they say will work. Some are thicker, some are thinner, they both have their reasons. Both companies are reputable, pick one, make a few phone inquiring phone calls and go...you can't go wrong, just need to make a choice.

I just completely redid my bottom last spring and used Interlux Interprotect 2000. They recommend a 10 mil finish thickness which ended up being 5 coats. To verify, I had a board that I measured the thickness of with a micrometer. With every coat I would run the roller over the board and measure the incremental difference which was typically 2 mils per coat, give or take. A gallon per coat just made it on my 320. The Interprotect 2000 is very easy to apply with a roller, basically just like bottom paint. One trick that I discovered is to cut a small piece of plywood or heavy cardboard and place over the roller tray while you're rolling, only lifting off to get more paint on the roller. This prevents a skim coat from forming. I especially found this to be a problem on the final coats of bottom paint, Interlux Micron 66, which dries very fast.
Good luck.

I to went with the Interprotect 2000, we put six coats to get the recomended 10 mil...It did a great job...I would suggest using the Micron cs or 66 after. What we did was use a different color of micron for the first couples of coats and then use the right color for your boat as the last coats...so when you start seeing the first color its time to put on a few coats....does that make sense to you? It lasted a couples of years before I had to touch up.....Not counting the Grounding.... Dan...
