Re: epoxy barrier coat sun exposure how long is too long?

Most manufacturers recommendations require a certain thickness regardless of the umber of coats. Interlux recommends 10mills, though how you get it is up to you. But it shouldn't take anywhere near 14 coats to get there, 4-5 is pretty typical.

I guess if you were doing an ultra high level racing boat, and applied very, very thin sprayed on coats it might take that many... But I have never heard of anyone doing that.
