Hydraulic jack. A good hydraulic jack is required for the removal of vehicle wheels before painting.
Wooden or iron horses are sometimes needed for this operation to support the vehicle with its wheels removed. Inspect
jacks prior to each use to ensure that they are safe for use (i.e. no leaks, cracks, etc.).
Supplies for preparing surfaces. Painting, removing, cleaning, rust-removing solutions, and sanding
materials are required for preparing surfaces.
Masking tape. Masking tape is required to cover all body parts that are to be protected from paint spray.
Tape alone is used to mask small areas. For larger areas, such as windows, the tape is used to fasten paper over the
area to be protected.
Sanding disks. Sanding disks are used with a motor sander and polishing pads and solutions are used with
an electric buffer.
Other tools. Other tools required in the paint shop include paint brushes, wire brushes for cleaning off loose
paint and rust, and putty knives or scrapers for removing old paint. Razor blade scrapers are useful for removing paint
from glass. A 16 ounce graduated glass container is needed for mixing paint and thinners in the required proportions.
Cloths. An abundance of wiping cloths is required for wiping off spilled paint and for cleaning spray guns
and related equipment.
Do not use electric sanders in a paint shop or near a spray paint area.
Electric Sanders. Portable, motor-driven, disk or orbital sanders are occasionally required for smoothing a
vehicle's body or fender before it is painted, although this is not usually the work of the paint shop.
Electric Buffers. Ordinarily, the same tool is not used for both sanding and buffing because the sander rotates
much faster than the buffer. There are combination sanding/buffers, however, that run at different speeds to
accommodate both operations.
Section III. DIP APPLICATION
5-16. WHEN TO USE DIP APPLICATION
The dipping method of applying paint is generally used for small articles and is especially suited to the coating of items of
irregular design that are difficult to reach by brush or spray; for example, the interior of a narrow tube. Dipping is not time
or cost effective except when a large number of items are to be painted in a production line manner. CARC primers and
coatings should not be used for dipping.
5-17. DIPPING TECHNIQUES
Ensure that the paint has been thinned to dipping consistency. Suitable consistencies vary with each article, and must be
arrived at by trial and error. Suspend the article with a cord or wire and immerse in paint. Remove the article slowly,
hang from a line, and allow it to dry in a comparatively draft-free location over a dipping tank or draining pan.
5-18. EQUIPMENT REQUIRED
A receptacle to hold the paint is required. This can be a pail or a specially constructed tank. In general, the receptacle
should be just large enough to conveniently permit the insertion of the article to be coated. Replenish the paint as needed
and use paddles to stir at frequent intervals. If the receptacle is large, a drain-off valve should be provided so that the
paint may be removed and placed in sealed containers when the dipping operations are completed.
