custom panel cloth

[FSUSHO]

Does anybody know the name or type of cloth used to build those crazy curved speaker boxes and custom panels? I know it's atype of fiberglass, but it's much smoother than your average fib cloth.

Also, any sources for it?

Thanks

Fiberglass. Nothing really special about it. Its usually sanded, smoothed with body filler to remove imperfections, then sanded again until the desired finish is achieved.

You can also use fleece or "mold fabric" to get the general shape, and add fiberglass to the back side. Its much easier to do the finishing work this way since the original surface is smoother, there is less sanding.
