Suction devices, in the past sometimes
called"plumber's helpers"or"glazier's helpers,"are tools that use a vacuum to
draw out a dent in metal, returning the panel to its pre-dented condition. They
are more effective on large expanses of metal -- such as door and wing panels,
hoods and trunks -- than on smaller and more convoluted areas. They do not work
at all on plastic body parts. Types of Suction Devices Small and shallow dents
can sometimes be pulled using a lavatory plunger, but a proprietary device is
likely to be more exact and effective. Some suction cup dent pullers are
designed to be used with an air compressor; they are attached to the inlet port,
which creates a strong vacuum within the cup. Once the cup is firmly attached to
the metal, it is pulled outward using an integral handle. This process, of
course, requires access to a compressor. Manual devices are marketed by numerous
companies that use an integral valve and pump handle to create the vacuum.
Integral Suction Devices Suction cup size and handle design are distinct
purchasing considerations in purchasing a dent-pulling device Autel

deformation, meaning that a 6-inch suction cup will repair larger dents than one
that measures 4 inches. A steel handle will stand up to more punishment than
aluminum, but the latter should be fine for infrequent home use. Some can be
pulled double-handed for more aggressive dent removal; twinned with a large
suction cup, these works well on fairly large deformities. Preparation It often
helps reduce the work the suction device has to do by mechanically reducing the
deformity first. Wrap a flat metal object that is larger than the dent in
several layers of cloth and hold this against the outside of the damaged panel
so that it covers the entire deformity. Gently tap the dent from the inside
using a flat-ended rubber mallet. An alternative to suction devices is a dent-puller
that is glued to the dent; these are notorious for pulling away paint Autolink

with saucer-like warped indentations. They are typically less successful with
dents where the metal is actually folded inward; a gouge where a line or crease
is within the deformation. Such dents can often be pulled out without extensive
bodywork and respraying by taking the vehicle to a professional"paintless
repair"body shop. Professional equipment is far superior to that sold to
do-it-yourself mechanics. In some larger metropolitan areas, technicians have
vans equipped for just this service, and the body shop can come to you. As with
all tradesmen, get a written estimate of the maximum cost of repair before
allowing the process to begin.
