The XactRC Traction Juice Bottle with Brush Tip features a 4oz bottle that’s just the right size for small or large hands! The replaceable brush tip is specifically designed for off-road use. With the brush tip, drivers no longer have to use both a sauce bottle and separate brush to apply. This is perfect for those who are tired of having their hands dirty from different tire sauces and chemicals. The translucent bottle allows for easy checking of how much sauce is remaining, it’s cleanliness or type of solution.
