This past weekend i wanted to really polish the rear rim on my nt . I first tried the hand method with mothers aluminum polish but soon ran out of patients . I went looking for polishing balls at the auot stores but found them to be too large . I ended up buying a couple from mc master carr . They are called felt polishing bobs , they have different shapes and sizes . I got the soft density for use with , gold silver , and aluminum . They have a 1/4" shank pit one in my drill and went to work . Two hours later what a difference they almost look crome . I was very pleased with the out come . Sure i could have done it by hand but didn't want to take a week to do it .
