If you're a newbie to polishing then the Das 6 pro is a good place to start. Give the guys at clean you car a call....they're very helpful and will set you in the right direction with a starter kit.
You'll basically need a 2 good sized buckets and grit guards, a lambswool washmitt, a bilthammer clay bar, detailer spray (any), some 3m tape, Das 6 pro, megs 105 and 205, then wax and sealant to complete the job
