212 to which reduction should be added 1-32 to 1-16 gallon of the enamel to each gallon of paint. This will assist in hardening the paint and the mixture can be used either on bare wood or over a sized surface. When the priming or first coat is thoroughly hard, putty with good hard-drying putty, one which will not turn yellow, then rub with fine sandpaper or steel wool, after which apply a second coat mixed flat, to which has been added a pint of the enamel to a gallon of paint. Rub this coat smooth with fine sandpaper or curled hair. Apply a good, smooth, even coat of enamel of good consistency. If properly applied, the enamel can be left in full gloss finish or lightly rubbed. If a higher finish is desired, reduce the first coat of enamel with a small amount of turpentine, one pint to the gallon of enamel. Rub this coat with fine steel wool to kill the gloss and level down the surface, then flow on a smooth, even coat of enamel. This can be rubbed to the finish desired and polished after three to four days' standing. If desired, zinc can be used for the flat coats in the foregoing directions; however, it is best to use lead for building up undercoats.

Zinc Finish. The priming coat for zinc should be as directed for flat work. Lead is best to use for priming or first coat over a sized surface. Where two or three coats of flat zinc work are specified, reduce zinc that has been ground in varnish with turpentine to a medium thin consistency and apply over a first coat of lead. When dry, rub with curled hair and apply a second coat of the same mixture of a heavier consistency. This will dry flat and make a beautiful finish.

If a gloss finish is desired, apply the finishing coat of zinc in varnish reduced with turpentine to a consistency of cream. To one part of this mixture add two parts white enamel varnish. If a higher finish is desired rub this coat with fine steel wool and apply a coat of clear varnish. This can be rubbed to the desired effect.
