AIIIGH finish of the paintwork is' not so much required on a commercial lorry as on a private car, but on motor coaches it is essential. However, the permanency of the work is just as important in both eases, and the necessity for frequent repainting adds con, fdtierably to the cost of maintenance. Efficiency in painting is only obtained_ by painting over a clean surface, and it is in the preparation of the suzface for the reception of the paint, that success or failure may lie. This applies Par
ticularly, to metal surfaces, the cleaning of which with emery cloth, etc., -may take several hours and involve a considerable amount of manual labour—a big expense.
To facilitate this work, a cleaner known as Deoxidine has been used with great, success for .some years in the finishing shops in America, and is now being adopted in this country by such well-knoWn companies as General Motors, Ltd.
The distribution of the cleaner in this
country has been pieced in the hands of 13rainco (1920), Ltd., St. Nicholas Street, Coventry. It is claimed that it removes rust and all other impurities and also prevents, the further formation of rust, and leaves the surface not only clean, but also slightly roughened, so that the paint more readily adheres. In use, the Deoxidine is merely applied to the surface, allowed to remain a few minutes, washed off,. and the surface dried, the whole process taking only a few' minutes.
