Re: epoxy barrier coat sun exposure how long is too long?
Without seeing it they could be anything from a bad fairing job, to slight water intrusion points, old repairs poorly done, ect...
The really question is if they are wet after cleanup then you may have some moisture in the hull. Since you are planning to keep the boat out of the water for a while anyway I wouldn't worry about it. In the spring come back and fair the hull with thickened epoxy, then reapply a barrier coat, then bottom paint and off you go.
