Query: Great & Gentle Brush!

I don't have a small fortune to keep refinishing damaged wheels, so this brush gets the job done safely. This brush works best on wheels that receive regular care. Really neglected wheels may require something a bit stiffer. All Zymol products are guaranteed, so if anything doesn't last a reasonable time, let your dealer know, and you can get a replacement at no charge.
