Alclad II question

[starmanmm]

I usually list what I had painted a praticular piece, but in this case I did not.

So my question is this... Can Alclad II be painted over Alclad II w/o first priming it black?

Just to let you know, I am not sure if the color was either duraluminum or polished aluminum that I had used. These two seem to be the closest match.

Would like to shoot it with the duraluminum (which is what I think it was) right over the existing Alclad II.

Thanks
