with all the choices out there,especially with the many types, names ,specific use's, etc.,etc.,that rustoleum has on the market; not to mention the wide variety of rattle can paints that can be had at wal mart or auto parts stores ,I think that unless you're using a product that is specifically marketed to the model airplane enthusiast like Klass coat or Warbird colors to name a couple,one should always do a TEST panel before using something on your plane. Even when a fellow modeler shows you his good results with one type of product and you purchase the same, theres still a chance the manufacturer may have changed the formula and your results could be very different. Again just my opinion.
