I use the Menzerna 2.5 pound polishing compound bar with four 12" buffing wheels stacked on a Hitachi 7" polisher. They make a coarse and fine compound. They say the coarse will take out 600grit scratches. I wet sand down to 3000grit and only use the fine compound; it's faster and gives a much better final buff. Finish with Maquiar's #5 Professional New Car Glaze to remove any remaining compound scratches (available at automotive paint stores).

I'd like to ask what any of you use to moisten your compounds if/when they start drying out? I'm using the DD3, 2L, 16 compounds in small tubs (500ml). Thanks folks, William R.
