Tom, I like to keep it simple. No primer. I sand the part as smooth as I can get it, then gloss black Testors enamel out of the can (I suppose you could use Tamiya gloss black, or any brand, really), polish out any obvious specks of dust or crud, then Spaz Stix out of the can. I suppose you could decant and AB everything, but takes away the whole reason why I like Spaz Stix... it looks so good right out of the can!
