I have the Aircraft Aluminum from Alclad and used a bit of it on my Ki-61. It's from Alclad's bright series of paints as opposed to Aluminum, Dark aluminum etc. Like John says I would test it out with the others.
Also, on the puttying of the wings I read that some P-51D's did not have them. These were typically the aircraft that arrived in the ETO painted in OD. These aircraft were later stripped of their paint to reveal the natural metal finish and the stripping agents the ground crews used (gasoline, kerosene etc.) removed the putty as well.
