A friend of mine actually removed his deck on his 125xxx series Laser and recored it because of extensive delamination. The original foam was definitely not Airex as it should have been. It seemed very much like polyurathane which is unsuitable for core. I've seen other boats with extensive delamination and suspect that they also have the wrong core since Airex is tough stuff. If this is the case with your boat, there is no resin you could use that will work for long because polyurathane foam is just too brittle.I have read many Laser Forum articles on delamination. But I still do not have a sense of what might be the best resin or glue or other adhesive to inject between the fiberglass skin and the foam core. Suggestions?
