Our Auto Brushes meet all requirements for strength, toughness and durability. The Auto Brushes are ultralight, nice to work with and extremely durable. They are 100% weatherproof and do not rot, rust or crack. They are also resistant to both heat and chemicals. The Auto Brushes come in two lengths – long and short – with and without rubber edges and soft grip. The rubber gives a better grip and protects the car or other item you want to wash.
