Get the Mezerna FG400 I'm telling you that you will not be disappointed.
take a look at the BMW 650 I did here:
BMW 650 Convertible detail and paint restoration
Deep scratches on the trunk and deep swirl marks throughout the entire body. Everything came out looking absolutely perfect with a high gloss shine even when using a medium cutting pad and no finishing pad. No holograms or light swirls left on the paint, just a perfectly smooth finish.
Plus if you wanted to you could switch from a heavy pad to a light pad mid process and not worry about mixing compounds.
It's totally worth the price and could save you hours working on the car.
