I haven't found a true blow by blow for Alclad application, but here are 2 links I'm sure you will find of interest.

From my own experience, I'll add that NMF's require the best seam work you can muster up. I've found the CA glues to be the best filler when required, and that means hitting the glue joint with some kicker and then working with sanding sticks from coarse to polishing stick withina half hour of gluing. As for Alclad in particular, it is really designed to be applied over a primer since it is strongly lacquer based. And it is designed to get varying shades by using the various colors they sell and taping off individual panels and spraying as you choose the colors. I have read of people using the SnJ polishing powder to achieve varying hues and shades of the same base color which is like using the SnJ technique with Alclad. I'm sure it would work, but I have never done it myself. As to the durability of the finish, Alcad is very durable adn can be fully taped over. I swear by Tamiya tape, but any low tack drafting tape should work just fine. The tough finishing system to work with is the metallizer line sold by Testors in their Model Master line. They are impossible to tape over without sealing and I have neve been happy with how the shades change when you clear coat it, so I use Alclad and SnJ. Personally SnJ is my favorite for airframes and I use ALclad Aluminum for landing gear struts that were painted silver laquer at the factory. Hope this helps and a few web searches will probably bring up a few more site for reference. Maybe Obiwan can charm in here, by te looks of his P-38 he knows a few tricks..........Good luck and have fune!!
