Green nylon bristles staple-set in a foam block with protective bumper, which wraps around the brush and protects the cars surface as you wash it if it happens to touch the paint. Use this brush with either a telescopic car/truck/RV wash brush handle, which is great for higher distances or the wood handle if length is not too much of a concern. This brush is perfect for washing cars and trucks and other vehicles with 3D Pink Car Soap since the bristles are designed to prevent scratching.
