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

Interesting about your barrier coat. When my boat was new I had the yard put a coal tar epoxy barrier coat on the hull prior to launch. That was 25 years ago with the boat spending almost it's entire life in the water with a haul out every several years for new bottom paint. I wish I could tell you that I have no blisters, but that is not true. Now I find out that the barrier coat is good for only about 10 years so my question is why apply it in the first place if it needs to be removed in 10 years. (I don't think you would just apply another barrier coat over the old coat.) Seems like removing a barrier coat would be harder than removing just the gel, but I expect to find out soon. Trying to get a good price on a peel and then letting it dry our for a year. Good Luck
