THOMAS & BROS. LTD. BRISTOL Laboratory Tests clearly prove... 'ZERO' Radiator Glycerine will not freeze, even at twelve degrees below freezing point. 'ZERO'—in solution as recommended for radiator use—shows no expansion on fall of temperature—thus absolutely obviating cracked cylinder blocks or burst tubes. 'ZERO' does not evaporate. 'ZERO' does not materially raise boiling point of circulating water—nor affect normal working temperature. 'ZERO' positively will not affect rubber, cotton, iron, copper, aluminium, etc., nor any part of the cooling system. 'ZERO' will not injure cellulose, paint, nor fabric finish. 'ZERO' has valuable anti-fouling properties. It renders rust and "fur" semi-colloidal—and thus prevents choked pumps and tubes. 'ZERO' is non-inflammable and non-odorous. | ||
