Most makers of model boats have found that it is practically impossible to give a model a pure white surface by painting it in the ordinary way with zinc or white-lead. After standing a day or two it takes a yellow or maybe a dirty white tinge. If the following directions are carried out in a careful and cleanly way, a pure white surface which will stand the test of time and sunlight will result: - After the model has been thoroughly glasspapered down, give it one coat of paint, made by mixing ordinary white French polish with flake white powder until it has the consistency of skimmed milk.
When this first coat has dried quite hard, rub it down with No. 0 glasspaper; dust the model and give it another coat of the same paint; repeat this process at least six times. Then give it another cat, but, instead of smoothing it with glasspaper, rub it down with powdered emery and. water, using a piece of hair-felt. Repeal this, and a beautiful white will be the result. Do not varnish it.
