I concur. However, an explanation of Alclad's aluminum colors. The polished aluminum is to represent what its name implies. Few aircraft skins were regularly polished- maybe squadron commander's plane, and older airliners (AA used to keep their skins very shiny). And, some military prototypes were highly polished as a showpiece for the vender. To get the polilshed appearance proper undercoat is essential.
Their regular aluminum is proper for most in-service aircraft. For really heavily weathered, beatup old planes the white aluminum looks proper.
