Personally, for the wings, I wouldn't use Alclad - but use it on the other areas, certainly.
The Mustang's wings were painted, so to achieve the contrast between the appearance of 'bare metal' and paint on the model, it might be better to use a straight silver paint for the wings.
One method I've used in the past, is to mix a very small amount of gloss white with the silver paint, which gives the effect of 'full size' silver paint, as opposed to the almost bare metal look of model paint. The 'very small amount' should be the equivalent to the tip of a paint brush added to the silver, and mixed in well, but of course, experiment on some scrap surface to achieve the desired finish - this can be done with a brush, before mixing for spraying. Too much white will give a slightly pearlescent 'metallic white' effect, which can be corrected by the addition of more silver.
This is also a very good way of simulating doped silver fabric, for example on control surfaces, by varying the amount of white added to the silver. Note the use of gloss white - using matt white will give a dull metal effect, as seen on, for example, undercarriage legs.
