I'm considering fabrication of an exhaust augmented duct for the cowl on the Rocket. It will be a single, flattened oval approximately 4hx8wx18l. This duct will handle all of the cooling exit air so it will see substantial volume of "warm" air, but will be augmented by raw exhaust flow (like a jet pump). I intend to line the inside with stainless foil tape, but I'm thinking a resin better suited to elevated temps than my typical West Systems would be a good idea.
Anyone have a line on a good high temp "hobbyist" product?
