Agreed. I like the boars hair wheel brush for delicate wheels.
I will have to agree with you on this. I have clear coated black wheels on my car. I ended up picking up a Boars Hair wheel brush as it is softer, to avoid the swirls created by the Mothers wheel brush which is nylon. The nylon brush works well on any other wheel such as a chrome or silver painted wheel. I do use the nylon wheel brush to give my tires a good swipe during a wash to keep the tire coating fresh and dirt free until the next application.
