This advertisement appears in Engineering News-Record, February 17, 1927 Underwater pipe lines are at the mercy of corrosion unless given properred-lead proteetfen For Submerged Steel this special protection Small quantity of litharge added to red-lead hardens the paint film-- It is of the greatest importance to brush out each coat well and to allow as much time as possible between coats. In this way you makes it more quickly water-resistant make sure that oxidation will be as complete as possible before the painted surface is PIPE lines, steel dock-work, canal locks, placed in contact with water. bridge piers--wherever steel work comes in contact with water soon after it is painted, Use this proven protective paint a special treatment is desirable.
