XCP ONE is a high performance multipurpose penetrating spray designed to penetrate, lubricate, displace moisture, as well as clean and protect against corrosion. It delivers maximum performance across a wide range of applications. It is the only maintenance spray used by The AA(Automobile Association), and beats products like WD-40 and other market leaders when it comes to loosening seized parts (as measured by the force required to loosen a treated rusted bolt).
