What does someone mean by describing a color as “golden?
My major point of view on this issue is that while any clear paint binder, including a varnish, might be used to hold the paint pigments (a la the interior aotake/aodake preservative coating) there is absolutely no hard evidence that the Japanese applied any non-pigmented material (clear coating) above the surface of an existing coat of pigmented paint. This scenario is possible, but heretofore it has not been documented or shown on existing wartime aircraft relics.
