Many foam cored composite structures, aircraft included (the cozy and velocity for example) use this type of foam. The smaller cell structure should actually be an advantage as it will take less micro to fill the cells therefore your finished weight will be reduced. The smaller cell structure is also an advantage over the larger variety in the sanding department as well, there is a much lesser chance of teasing pieces out during the sanding process, leading to the addition of yet more micro to smooth the surface. As to why the micro isn't taking to the surface of the foam is a bit of a mystery. I'll see what I can find out. Cheers. Peter Bancks [email protected]
