DAS Polisher

+1 for 3M stuff, I saw it being used at the high end bodyshop we visit annually so decided to try the perfect-it polish. Not cheap (about £35 for a 1 litre bottle) and has to be machine applied, but so much better than AG SRP, no white filler in all the crevices and a lovely shine on the car. I top it off with AG HD wax.
One small point - if the OP decides to invest in a DA, also get some 3M 25mm blue low tack masking tape for all edges, glass seals etc, and as Mercy Me says, prepare the paint thoroughly before starting the correction - you might want to consider adding a spray with Iron-X or similar, then rinse off, to remove brake dust before claying the car.

I'm not an expert but there seems to be general agreement that whilst rotary will produce better results they are harder to use and more suited to professional use, as an amateur orbital are safer and easier to use.

You may find that having used a machine once you may decide to use more often....
