The stock rims on my 94z or in the how to under appearance... i see that he has them that clean, but how do you get all the hard to get spots that i can never get, these stock rims are so hard to clean, i can never get all the stuff off in those hard to get places, and there is no way to sand it.... so if someone could tell me how they get all of it off like in the picture of the how-to i would appreciative. Thanks
