in the where corrosion works unseen `Three coats ofpure red-lead most practicable method ofprotecting buried steel STEEL buried in the ground is threatened by un usual danger from corrosion. The surrounding earth is nearly always damp. Ground water is a constant menace to the metal. Under most conditions, the most feasible method of protec tion is a three-coat covering of pure red-lead. Paint made of red-lead adheres closely to steel. It is moisture-proof. It is not affected by the chemical sub stances that are ordinarily found in ground water. It offers dura ble, economical protection. Where the soil condition is strongly alkaline, of course no paint issuitable. In such a case, the oil vehicle of the paint will be turned to soap. Tanks sunk in the ground are sometimes protected as follows: Three coats of red-lead are ap plied. The tank is then buried in sand, which acts as a filter. In damp soil, a metal tank so treated will last for many years without further attention. In dry soil it will last even longer. Red-headfavored A questionnaire showed that oil men in every oil field in the United States favored red-lead for metal protection. Fifty-three oil men answered. Thirty-two (or 3 out of 5) are red-lead users. Dutch Boy red-lead was pre ferred by many of these oil men. You can get it in either paste or liquid form. The liquid comes in the orange-red for next-to-metal coats and in greens, browns and black for finishing coats. The paste comes in the orange-red and can be shaded to dark colors. Tanks and tank cars painted in light colors guarantee a large yearly saving in oil. Dutch Boy white-lead is ideal for reducing evaporation losses in thismanner. And used over an undercoating of Dutch Boy red-lead it not only cuts your evaporation losses to a minimum, but gives the same weather protection. We shall be pleased to help you solve; any question of metal protection. Specialists on our technical staffhave made a study of paint for the oil industry. Their assistance is free of charge.
