While on subject of foam, maybe someone would consider my question. I'm a new KR2 owner/builder having bought a KR2 about 80% finished, i.e. all of the fiberglass work is done except some miscellaneous. This kit was started in 1974 or so and the foam at the end of the stub wings is pretty "boogered up" and, in a few areas, sort of crumbling. The fiberglass/resin job is really strong with a good bond. I don't know know what type of foam was used, but the former builder did say that that this foam can not be cut with a hot wire device due to the toxic gas that it would emit. As far as the ageing and crumbly state of the foam, do I have a problem?
