    What is required to get a blue sky when it is not great (excluding post
    processing)?

    Graduation filters make the sky more interesting, polarizer's make it more
    interesting, but is there a filter which is designed just for making skies
    bluer?

    No.
    If it ain't there you can't fool the camera into thinking it is if ND,
    polarizers, UV filters and exposure adjustment won't work.
    Learn to use Photoshop to fake it.

  3. Anything that darkens a light, pale blue sky will increase its saturation,
    making it appear bluer. Therefore polarisers and ND grads will actually
    make the sky bluer. Another option is to simply expose for the sky, though
    this will sacrifice the rest of the photo, most likely. The idea is to get
    a large difference between the blue and the red channels - the more this is,
    the higher the saturation. Well, that's the theory - tell me if it works.

    If the sky really is overcast, and definetely not even slightly blue, then
    I'm at a loss at what to do, apart from putting a blue grad filter and not
    worrying about clouds looking blue.

    You could try shooting Tungsten film under daylight conditions. Of course,
    that would make everything more blue, though you can knock that down a little
    with a slightly orange filter (not strong orange).

    Weird Cokin coloured grad filters. The problem is that the have a somewhat
    definite edge, and that might show up in the images. Definitely low cost
    enough to try out one or two.

    A really strange way to do this would be to cross process some colour
    negative films in E-6. Depending upon the film, the blue effects will vary.
    The other colours will also go a bit off as well, so unless you want a
    slightly surreal look, cross processing might be fun, but not a solution.
