Long lasting wax / polish

[trickywoo]

I'm looking for something thats good for 3 - 6 months (over the worst of the winter). None of the 'natural' carnauba based stuff lasts more than a month at most. It gives a nice shine and is easy to use but the beading is gone inside 4 weeks (I've tried various stuff from meguiars and zymol).

The only stuff that beads for a long time is the Autoglym super resin polish but I know its not kind to paint and its not very nice to use.

Also I don't want to be spending ££££.

Any recommendations from experience?

Thanks for the replies! The Zaino looks good. Its just a shame that as usual we have to pay more in £ than it costs in $ in the USA. Not sure my banger is worth it.
