g10 and g11 (g10 with melamine added for self extinguishing properties) are both 'chemically resistant'. Because it's resin and fiber glass, neither material takes up moisture or will hold the chemical for extended periods of time. Both do not discolor with kerosene or bleach. My biggest concern with micarta's is the fabrics used, all of which can take up some amount of a chemical and hold it becuase they are fibrous in nature, expecially heavy fibers like burlap, denim, and canvas.
I can't wait until nootkatone becomes a readily available repellant, because it's gonna be soooooooo much nicer to use than deet. It's octapamine, something we don't have receptors for thats common in grapefruit. In insects, it's the equivelant to adrenaline, it attacks the receptors for it causing them to shake to death.
