looking at some of your threads i think i know what to get but still not sure. basicaly my car is 10 years old and has the usual scratches and swirls etc. i have a shot of a machine polisher that i used on the boot i painted myself to get rid of some orange peel with some g3 i had and a compound head. i want to go over the whole car to get the worst of the marks (mainly awirls) out and be left with a decent finish so i can wax it. what would you recomend and what sort of pad to use with it? i have some g4 as well but im not too sure what its best for. thanks
