| RAD The Sensible Safeguard Is the trade mark under which PEARCE's SPECIAL MOTOR ANTI-FREEZE COMPOUND is now marketed. A tin is sufficient for the average car for the whole winter. Used as directed it will ensure that the water in your radiator will not freeze and it is quite unnecessary to employ special heating devices to prevent freezing of the cooling system. Every owner of a motor car in the winter fears the possibility of the water in his cooling system freezing and involving him in heavy expenses owing to a cracked cylinder or broken radiator. Even the most dependable of cars are subject to climatic conditions, and freezing can occur when least expected. Why spend another winter worrying whether you may freeze up when for 12s. 6d. you can ensure absolute immunity from frost troubles? The directions for use are simple—see back page—and one filling suffices for the most severe winter. RAD cannot freeze. A 20% solution will withstand 11° of frost; a 40% solution will not freeze at zero. Although first marketed as recently as 1925, RAD has already become an absolute necessity for all discriminating motorists. Recommended by Entire Motoring Press.
