If necessary, drill a hole in the brush handles for suspension in the keepers.
Use enough oil, solvent, or thinner in the keeper so that the bristles of the brushes are covered. These
brushes should not touch each other or the bottom of the container. Brushes kept in linseed oil should be cleaned before
use by washing in thinner.
Brushes used for CARC, lacquer, synthetics, or shellac should be placed in brush
keepers containing CARC thinner, lacquer thinner, synthetic thinner, or alcohol,
respectively. Traces of linseed oil will spoil such materials and the finishing job
performed with these brushes.
For rollers, follow the manufacturer's instructions.
Indefinite Storage. When brushes are not to be used for a long time, they may be prepared for storage as follows:
Immerse in raw linseed oil or another appropriate thinner for a few days. This can be done in the brush
Remove from the keeper and press out most of the thinner.
Straighten the bristles and wrap the brush in paper. Brushes treated in this manner should be stored flat
with no weight applied to the bristles. Open the package and repeat the procedure every six months or less.
A procedure similar to this should be followed for storage of rollers. Follow the instructions given by the
manufacturer for these items.
5-15. MISCELLANEOUS EQUIPMENT
Scrapers. Scrapers of various sizes, made of bronze, which do not produce sparks when rubbed on other metals
or concrete surfaces, are used for cleaning paint residue from spray booths, the floor, and from metal and wood surfaces.
Flexible carbon scrapers should be used on aluminum and magnesium since metal scrapers may leave deposits of metal.
These deposits promote galvanic corrosion, and in some instances, could even cause shorting of electrical circuits.
Brass stencils. Brass stencils in one to four inch sizes are sometimes used for stenciling.
Star-insignia cardboard stencils are available in various diameters.
Paper stencil sets are available in various sizes.
Gummed-back paper stencils. Gummed-back paper stencils are available for applying registration
Miscellaneous Tools and Supplies.
Layout Tools. Straightedges, a yardstick, a steel square, and dividers are used for laying out lines to guide
in the location of letters and insignia when stenciling. Guidelines can also be made by snapping chalked string against
the surface to be painted.
