i personally use bilt hamber clay http://www.theultimatefinish.co.uk/bilt-hamber/auto-clay-original.aspx, it is awesome stuff and can be used with water as a lube. Caranuba wax is brilliant stuff too.. i use dodo juice, its great to use and gives a great finish. you can get a panel pot http://www.theultimatefinish.co.uk/dodo-juice/supernatural-panel-pot.aspx which will do a fair few passes over the car, then if you like it you can invest in the bigger one.
