Just about to do mine in the next few days , I will do what i have always done when the rims get shabby . I use a set of mushroom headed mops on a die grinder with blue soap , then polish off with a soft cloth and Vienna lime and finish with a clean mop again in the grinder. It takes no longer and is a lot less hard work than autosol . The results are awesome and last a good couple of years . The key to it all is the Vienna lime , basically a finely powdered calcium carbonate . It takes off all the greasy smut that usually makes this kind if polishing harder than it's worth . If the wheels are badly tarnished , start with a brown soap to cut thru the grime , change the mops and then finish with the blue or a white !
If you don't have a die grinder , a cordless drill works almost as well .
