The stickiness of an oilskin coat which has been dressed with a mixture of boiled oil, terebine, and oil Tarnish may be due to the use of inferior materials, though it must be remembered that mixtures do not always dry quickly. Boiled oil, oil varnish, and terebine are rapid driers, and when excessive amounts of driers are present the mixture hardens rapidly on the surface and but slowly throughout, the film remaining tacky for a long time. The mixture should dry right through equally, and therefore not too rapidly. Boiled oil alone is a good preparation, but a little gold size may be added if desired to make it. dry more rapidly. The oil should be applied in a thin coat, the oilskin hung up in a warm place till quite dry. and a second coat applied and also allowed to dry. As it is doubtful whether it is possible to get rid of the stickiness, it is perhaps better to steep the oilskin in benzoline for a time, dry it in the open air, and treat it as above.
