The problem of retention of oil was undertaken first, since it was considered possible to properly design a container to carry one hundred pounds.

It was realized, at the start of the development of this container, that it must meet certain special require ments, the two outstanding being:
(1) Oil-proofness, so that it would retain the paste without loss of the linseed oil and volatile thinner.
(2) S|rengtlf^of construction, so thait it would carry safely the heavy weight encountered in lead pastes.

However, the ma jority of the present day paste is soft paste which, while about the same weight as heavy paste, contains vola tile thinner in addition to linseed oil. Such a paste is much more mo bile than the heavy paste, and a seri ous vehicle loss would.,Jesuit. if the

TWO PAINTS WITH BUT A SINGLE PURPOSE
...to produce stand out two-coat jobs that stand up
No question about it -- it takes a paint with lots of lead to give you jobs with lots of looks and lots of life. The Dutch Boy Two-Coat System teams up a pair of paints that are loaded with lead: The Primer is an ail-lead paint ... and so is the Outside White. No wonder Dutch Boy Paint users consistently turn out^stand out job's^iat really do stand up.
