You can also get Rain-X wipes, which are easier to use. I didn't like the stuff though... made my wipers judder (and the still do) almost a year later.
Polish-wise, there is some really expensivce stuff out there (i.e Zaino) but I'm not willing to part with my hard-earned
, especially being skeptical of some of the claims made.
I've used Maguires 3 step (beacuse Halfords had a 'buy 3 pay for 2' offer on car care products and can honestly say it was really good. Ok, its hard work as you have to go over the car 3 times (once with each 'step' - paint cleaner, polish, and then carnauba wax), but it trully was worth it. Took me about 6 hours though, but I clay barred the car first as well
Probably works best on a dark coloured car though.
Also, the 3M stuff (especially the hand finesse) is really good on dark colours, but this is for available to the trade only I believe.
