Fillers

I have gathered the following thickeners and fillers to experiment with. Cabosil, fumed silica, wood flour, a new cellulose one from MAS, phenolic microballoons, flyash, lint, chopped glass, polyester waste, line tow and I think that's it
I want to run tests for sag, water absorption and fillet strength. Keep tuned.

I'd like to know if the colored Kevlar is more UV resistant than the plain yellow and if you paint it over or cover it with carbon fiber is that enough protection to keep it from degrading. Newt told me some great stories about kevlar sails blowing out during ocean races.
