STANDARD PROCEDURE - PLASTIC BODY
PANEL REPAIR
There are many different types of plastics used in
today’s automotive environment. We group plastics in
three different categories: Rigid, Semi-Rigid, and
Flexible. Any of these plastics may require the use of
an adhesion promoter for repair. These types of plas-
tic are used extensively on DaimlerChrysler Motors
vehicles. Always follow repair material manufactur-
er’s plastic identification and repair procedures.
Rigid Plastics:
Examples of rigid plastic use: Fascias, Hoods,
Doors, and other Body Panels, which include SMC,
ABS, and Polycarbonates.
Semi-Rigid Plastics:
Examples of semi-rigid plastic use: Interior Panels,
Under Hood Panels, and other Body Trim Panels.
Flexible Plastics:
Examples of flexible plastic use: Fascias, Body
Moldings, and upper and lower Fascia Covers.
Repair Procedure:
The repair procedure for all three categories of
plastics is basically the same. The one difference is
the material used for the repair. The materials must
be specific for each substrate, rigid repair material
for rigid plastic repair, semi-rigid repair material for
semi-rigid plastic repair and flexible repair material
for flexible plastic repair.
Adhesion Promoter/Surface Modifier:
Adhesion Promoters/Surface Modifiers are required
for certain plastics. All three categories may have
plastics that require the use of adhesion promoter/
surface modifiers. Always follow repair material man-
ufacturer’s
plastic
identification
and
repair
procedures.

PANEL SECTIONING
If it is required to section a large panel for a plas-
tic repair, it will be necessary to reinforce the panel
(Fig. 1). To bond two plastic panels together, a rein-
forcement must overlap both panels. The panels
must be “V’d” at a 20 degree angle. The area to be
reinforced should be washed, then sanded. Be sure to
wipe off any excess soap and water when finished.
Lightly sand or abrade the plastic with an abrasive
pad or sandpaper. Blow off any dust with compressed
air or wipe with a clean dry rag.
When bonding plastic panels, Follow repair mate-
rial manufacturers recommendations. Be sure that
enough adhesive has been applied to allow squeeze
out and to fill the full bond line. Once the pieces
have been brought together, do not move them until
the adhesive is cured. The assembly can be held
together with clamps, rivets, etc. A faster cure can be
obtained by heating with a heat lamp or heat gun.
After the parts have been bonded and have had time
to cure, rough sand the seam and apply the final
adhesive filler to the area being repaired. Smooth the
filler with a spreader, wooden tongue depressor, or
squeegee. For fine texturing, a small amount of
water can be applied to the filler surface while
smoothing. The cured filler can be sanded as neces-
sary and, as a final step, cleanup can be done with
soapy water. Wipe the surface clean with a dry cloth
allowing time for the panel to dry before moving on
with the repair.
PANEL REINFORCEMENT
Structural repair procedures for rigid panels with
large cracks and holes will require a reinforcement
backing. Reinforcements can be made with several
applications of glass cloth saturated with structural
adhesive. Semi-rigid or flexible repair materials
should be used for semi-rigid or flexible backing rein-
forcement (Fig. 2) and (Fig. 3). Open meshed fiber-
glass
dry
wall
tape
can
be
used
to
form
a
reinforcement. The dry wall tape allows the resin to
penetrate through and make a good bond between
the panel and the adhesive. Structurally, the more
dry wall tape used, the stronger the repair.
Another kind of repair that can be done to repair
large cracks and holes is to use a scrap piece of sim-
ilar plastic and bond with structural adhesive. The
reinforcement should cover the entire break and
should have a generous amount of overlap on either
side of the cracked or broken area.
When repairing plastic, the damaged area is first
“V’d” out, or beveled. Large bonding areas are desir-
able when repairing plastic because small repairs are
less likely to hold permanently. Beveling the area
around a crack at a 20 degree angle will increase the
bonding surface for a repair (Fig. 4). It is recom-
mended that sharp edges be avoided because the
joint may show through after the panel is refinished.
• Panel repair for both flexible and rigid panels
are basically the same. The primary difference
between flexible panel repair and rigid panel repair
is in the adhesive materials used (Fig. 5).
