its probably been posted before but ill ask anyway,i have a bmw e46 as my daily driver ,when i bought it 5yrs ago i could tell it had been machine polished and in certain light the swirl marks look terrible, wots the best and easiest way to remove these,do i use like a finer grade of a g3 product or can i use a polish i have bought a polisher to help cut down the effort but do i use a sponge or a wool bonnet cheers
