Just having fun with vessels. My neighbor has a vessel that has continuously had blister issues. Unfortunitely, and ultimately it has to do with hydrolysis of the polyseter resin in the gelcoat and laminate. This is the fourth time the issues have occured. I informed him that I would put a post on my site to obtain any suggestion what to do about this on-going problem. He's already pulled her out of the water and plans on working on her after the winter...any ideas or suggestions of deterrent to stop or at least slow this process. I myself have only dealt with one issue on my old vessel and one only. I had the bottom completely redone as in new paint, new gelcoat...but this issue with my neighbors vessel is non-stop.
