Hi Guys,i made a start on my Pro Class rims today which are pretty beat up,but straight with loads of small scratches and nicks which are repairable,and after an hour and a half there is a difference to when i started but i need some advise.I have a bench grinder 3000 rpm with 4 inch mops about an inch wide,green soap to start and blue to finish.The sides of the rims have turned out amazing but at the rate of what i have done it will take about 10 hours to finish so is there any way to speed up the process or am i doing something wrong or maybe a wider mop?
