My landsailing buddies use extruded styrene to build their land yachts when using epoxy resins and polyiso when using polyester. So, while styrene may be a workable short term fix, I would certainly prefer a proper repair. With foam core construction one can approximate the building process, but that is not going to be possible for anyone outside of Sweden on a Marstrom. It's highly unlikely that even Marstrom re-autolaves his own repairs. Mike, what is your suggestion? Are corecell and/or baltek better?

It was Mike's post about his repair ordeal that got me thinking (and now inquiring) about the difficulties of dealing with nomex. As I stated above Fred Smith assured me that is no big deal but now I'm becoming more concerned. Steve
