Builders of aircraft like the Rutan Long EZ have used expanded polystyrene and polyurethane foams for decades. These materials can be cut with a hot wire or carved and sanded into complex curved shapes, joined with a slurry of epoxy and microballoons, and covered in fiberglass and epoxy. When completely surrounded by fiberglass, the resulting composite structure is completely waterproof and immensely strong. Dissimilar materials like aluminum and wood can be fiberglassed to the structure to form structural attachment points and other features, or through holes surrounded by epoxy can be built in to provide attaching pads for bolts.
The boatbuilding industry also has extensive experience with wood and foam cored fiberglass structures.

Early on when dacron was still new and cotton/dope was still the only "approved" method, Fisher had a system that used lated house paint in conjunction with aluminum powder as a UV block. I don't remember the details, but it had good success and was inexpensive compared to the "approved" materials.tony.latham wrote:I'm pretty sure that PMF evolved out of Fisher Flying Products covering system.
It looks like they are using dacron and Stewert Systems Adhesives?? Whatever that goo is?
Thanks,
