Hi Fred!
Interesting comparison, but I have to defend Alclad a bit here.
Alclad have several different Aluminium colors in their range (white, regular, dark, dural-, polished).
If you want a really shiny ac, you should use "Polished Aluminium" (over gloss black!) that gives the shine as Floquil does.
The "regular" Aluminium gives a more dull metallic surface, wich I prefer on a "used" airframe.
Sorry to say, but I have never seen any Floquil paint here in Sweden, would have been nice as they have a lot of those elusive railroad colors (Warbonnet Red, Armour Yellow, Harbour Mist Grey to name a few).
Just my points of view, your P-47 looks really good!
Can´t wait to see her with decals on!
Cheers!
