Hi Dave,
It worked quite well I'm happy to say. I primed the model with Alclad Gray Primer and Microfiller then sprayed it with their Dark Aluminum. After drying overnight I polished it out with some 1200 sandpaper and a tissue (yes, a tissue). I then sprayed the AK on the whole model with a bit heavier application on the areas I intended to really "work on". I let that dry about 45 minutes then sprayed the Mr Color. I let that dry about 1/2 hour then started picking at it with a toothpick. I also used some Scotch tape to peel some off. I have to say I was pretty pleased with the way it all worked out and just might do another Japanese a/c although WW II Japanese stuff isn't high on my list of "likes". PM me if you have questions.
