Chrysler 300/300 Touring/300C, Dodge Magnum. Manual — part 2114
ROAD TESTING WIND NOISE
1. Drive the vehicle to verify the general location of the wind noise.
2. Apply 50 mm (2 in.) masking tape in 150 mm (6 in.) lengths along weatherstrips, weld seams or moldings. After
each length is applied, drive the vehicle. If noise goes away after a piece of tape is applied, remove tape, locate,
and repair defect.
POSSIBLE CAUSE OF WIND NOISE
•
Moldings standing away from body surface can catch wind and whistle.
•
Gaps in sealed areas behind overhanging body flanges can cause wind-rushing sounds.
•
Misaligned movable components.
•
Missing or improperly installed plugs in pillars.
•
Weld burn through holes.
STANDARD PROCEDURE
STANDARD PROCEDURE - HEAT STAKING
1. Remove trim panel.
2. Bend or move the trim panel components at the heat staked joints. Observe the heat staked locations and/or
component seams for looseness.
3. Heat stake the components.
a. If the heat staked or component seam location is loose, hold the two components tightly together and using
a soldering gun with a flat tip, melt the material securing the components together. Do not over heat the
affected area, damage to the exterior of the trim panel may occur.
b. If the heat staked material is broken or missing, use a hot glue gun to apply new material to the area to be
repaired. The panels that are being heat staked must be held together while the applying the glue. Once the
new material is in place, it may be necessary to use a soldering gun to melt the newly applied material. Do
not over heat the affected area, damage to the exterior of the trim panel may occur.
4. Allow the repaired area to cool and verify the repair.
5. Install trim panel.
PLASTIC BODY PANEL REPAIR
There are many different types of plastics used in today’s automotive environment. We group plastics in three dif-
ferent categories: Rigid, Semi-Rigid, and Flexible. Any of these plastics may require the use of an adhesion pro-
moter for repair. These types of plastic are used extensively on DaimlerChrysler Motors vehicles. Always follow
repair material manufacturer’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 Poly-
carbonates.
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 manufacturer’s plastic identi-
fication and repair procedures.
SAFETY PRECAUTION AND WARNINGS
WARNING:
•
Eye protection should be used when servicing components. Personal injury can result.
•
Use an OSHA approved breathing mask when mixing epoxy, grinding, and spraying paint or solvents in
a confined area. Personal injury can result.
•
Avoid prolonged skin contact with resin, petroleum, or alcohol based solvents. Personal injury can
result.
•
Do not venture under a hoisted vehicle that is not properly supported on safety stands. Personal injury
can result.
NOTE:
•
When holes must be drilled or cut in body panels, verify locations of internal body components and elec-
trical wiring. Damage to vehicle can result.
•
Do not use abrasive chemicals or compounds on undamaged painted surfaces around repair areas. Dam-
age to finish can result.

PANEL SECTIONING
If it is required to section a large panel for a plastic
repair, it will be necessary to reinforce the panel. To
bond two plastic panels together, a reinforcement
must overlap both panels. The panels must be “V’d” at
a 20 °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 material
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 necessary
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 reinforcement and open
meshed fiberglass 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.
