Bill the underside of the coupe hoods use 11oz. Of graphite then topped with 14 oz. of aluminum. We also do the underside of the roof and pillers and that uses 8 oz. of graphite and then 10 oz. of aluminum. Total thickness is about 6mils before polishing.
Bill we aluminum plate high end flying models like the one in my photo. The process is the same but we do a micro plating on them so as to keep the model as lite as possible. We added less weight than paint. Total weight gain on this p-47 was 16oz.
