If you want results like the pro's wash thouroughly first, then use Meguiars 105 ultra cut compound to get rid of paint oxidation, follow with Meguiars 205 ultra polishing compound, and finally a good wax. Needless to say you need to use a good polisher like a porter cable 7424xp or you will just be wasting time. If you want to go the extra mile clay bar all surfaces before using any of the compounds above. If you just use the stuff above, however, I think you will be very pleased.
