Paints as a Prevention of Corrosion

When the paint is too thin the heavy particles of lead gravitate downwards, and so it happens that a thicker deposit is formed on certain parts of the surface by partial denudation of other parts, and if a suitable portion of paint skin cut from a vertical painted surface were examined under the microscope this would be readily observed. The obvious remedy for this would be to fill the paint up with dryers so that the lead would not be given time to settle, which remedy is as bad, if not, worse, than the evil. If such paints are used it is at all times necessary to rub well into the surface inequalities of the metal and to use sparingly, since the adhesion of the first coat is of prime importance. H.
