fiberglass
I've been getting supplies at Home Depot,Lowes, O'Reiley Auto Parts,Auto Zone,Wal Mart,NAPA,Pep Boys.You can shop around for price.-------- Many fabrics will work.Dacron is not one of them.It's used as a peel-ply in polyester work.--------- The bi-axial fiberglass "drapes" nicely over compound curves.Staggering consecutive layers of the cloth's bias of weep and woof builds tensile strength.----------- Epoxy has advantages over polyester although you need to look at price.------- If you work with Carbon fiber,treat it as you would asbestos.Some universities forbid the students from working with it due to a perceived inhalation health risk.---------- Always use a good form-fitting respirator.If you have facial hair as I do,coat your cheeks and jowls with petroleum jelly to get a good air seal ( applicable for spray-painting also!).-------------- Also,it's preferable to use air-driven power tools for grinding and sanding as composite dust is very destructive to open frame electric motors.
