should be corrected by resealing. Attaching points of
new replacement panels should be resealed (Fig. 10).
Flanged joints, overlap joints and seams should
be sealed using quality sealer of medium-bodied
consistency. Sealer used must retain its flexible
characteristics after curing and be paintable.
Open joints which require bridging of sealer to
close a gap should be sealed using a heavy-bodied
caulking material.
Manufacturers' labels should be checked for
material usage, recommendations, characteristics and
application instructions.
Color application may be required to restore
repaired areas such as engine compartment, underbody
and inner panels to original appearance. When this is
necessary, conventional refinishing preparation,
undercoat buildup and color application techniques
should be followed.
Deadener materials (spray-on type) are used on
various metal panels to provide corrosion resistance,
joint sealing and control the general noise level inside
the passenger area of the car. When deadeners are
disturbed because of damage, removed during repair
operations, or a new replacement panel is installed, the
deadener material must be replaced by a service
equivalent material. The application pattern and
location of deadener materials can be determined by
observing the original production installation.
Anticorrosion compounds are light-bodied
materials designed to penetrate between metal-to-metal
surfaces, such as pinch-weld joints, hem flanges, and
integral panel attaching points where metal surfaces
are difficult to coat with conventional undercoating
materials, and are inaccessible for painting. Materials
suited for this type application are 3M Rust Fighter-1
(part no. 08892) or equivalent.
Conventional undercoating is recommended to coat
large areas such as floor pan sections. The material
should not be applied to any moving or rotating part,
energy absorbing bumper components, shock absorbers
or on the floor pan in the area of the catalytic converter.
After undercoating, care should be taken to assure that
all body holes are open.
Sequence of application steps for anticorrosion
materials is as follows:
1. Clean and prepare metal.
2. Apply primer (acrylic chromate).
3. Apply sealers (at all previously sealed joints).
4. Apply color in areas where color is required, such
as hem flanges, exposed joints and underbody
components.
5. Apply deadeners (as indicated by original
application pattern).
6. Apply anticorrosion compounds.
7. Apply underbody rustproofing material.
Cleaning of interior and underbody panel
surfaces is necessary when original galvanized or other
anticorrosion materials have been burned off during
welding or heating operations. Removal of the residue
left from burning will require additional care in such
areas as interior surfaces of box-type construction and
when configurations of the metal panels limit access to
