Alclad isn't tricker than any other metalizer.
The key to the high-shines (polished aluminum, airframe aluminum, chrome, stainless steel) - which you'll need to get that kind of finish - is a very smooth gloss black base coat*. The high-shines are semi-translucent and depend on the undercoat to provide depth.
*you can use other colors to introduce variation, but for a first go, stick to black.
Other than that, it's all about misting it on and building it up in very light coats, exactly as with other metalizers.
Here's a P-51 I built last year in airframe aluminum:

Ultimately I was going for a more oxidized finish...and the other cool thing with the nature of the high-shine finishes is that that translucency makes them darker than the regular finishes (Aluminum, Duraluminum, etc) and thus excellent for shading...
