i have a black 2004 grand prix gt thats in desperate need of swirl removal. i've never used a machine polisher before but i plan on buying thr pc 7424. i've also heard a lot of good things about menzerna so i'll probably use thier products. i was just looking for advice on the exact products, pads, and steps i should be using. this car is my baby and i want to make sure i don't damage it. also i live in michigan and wont be doing it until it warms up, so i have some time to put a good plan together. thanks.
