I have a Pica Waco that is finished with Cream and Missle Red Monokote. I managed to find a can of the now discontinued Cream LustreKote and painted the aileron skins with it to match the rest of the wing. Everything turned out great, but now that I have been flying it for the last month the tops of the ailerons are turning a dark brown. The undersides remain unaffected. I am thinking that this is a UV issue or something. Does anyone have any suggestions as far as a UV blocking clear coat or something? I have already repainted them once and the problem has returned.
