Preventing swirl marks is one of the biggest challenges in caring for today’s delicate clear coat finishes. Grit Guard® helps prevent swirl marks inflicted during the wash process when small particles of dirt and debris are rubbed across the surface of the paint. Each time you dunk your wash mitt into the bucket to get more suds, rub it against the Grit Guard®. This will help remove the dirt and leave it at the bottom of the bucket. Supplied with a 18.9 ltr bucket, in which the Grit Guard® snugly fits.
