Need high-temp "rubber" coating Hey I'm looking to coat some 0.5" aluminum rods with some sort of coating to increase the friction coefficient ("tackiness" I believe it's called). It will be used in high temperature environments of up to 200C. Does anyone know of such product? I tried calling this company but that product can't get anywhere near 200C. http://www.plastidip.com/home_solutions/Plasti_Dip Thanks!
