Everyone needs at least 3 buckets in their detailing arsenal. One for washing, rinsing, & wheels! Each bucket comes with a Grit Guard & Gamma Seal Lid. The Grit Guard serves as a washboard for the wash pad, keeping dirt off your pad and your vehicle. The Gamma Seal Lid quickly and easily turns our 5 gallon bucket into a waterproof and airtight container with a simple twist of the wrist.
