I'm currently doing a P-38 Lightning Eggplane by Hasegawa. I used Mr. Color 8 Silver. Decals aren't a problem on it, but the reason I asked about your paint is because I have heard of decals having a hard time with metallic paints. I did some tests for a clear coat. The lacquer Mr. Color clear dulled the silver. Future was better, but Alclad's Aqua Clear was better. It still isn't as nice as the base paint, but it's good to seal the decals. I have only ever used Alclad's Chrome, and I have a problem with it rubbing off from just touching it. I assume that the aluminum color does not have this issue?
