rd_volvo, another factor is the condition of your paint and what you're prepared/have time to do.
If you paint is perfect (no swirls/scratches) then I'd:
1) Wash then clay (if you have some - if not, a must to have - if you get the Mothers Clay Kit you get an excellent clay and one of the best OTC QDs, and best OTC cleaner wax)
2) Prewax cleaner (Megs Step 1 is better than Mothers Phase 1)
3) Reflection Wax followed by Reflections Top Coat x 2 (better than NXT, IMO)
If you have swirls and are in a position to polish them out, then clay, and then use PowerPolish and two different pads (medium and light polishing), followed by step 3 above.
If you have swirls and can't polish then:
1) Wash and clay
2) Prewax cleaner
3) Mothers Phase 2 glaze (Megs step 2 Polish very good too)
4) Cal Gold Carnauba or even better, Reflections Top Coat x 2 (no Reflections Wax as its mild cleaners may remove some of the glaze.
