Apply polyester filler (only onto bare metal).
Apply filler.
Lightly sand the whole component.
Thoroughly clean with silicone remover and rub dry.
Apply corrosion protection primer to bare areas.

The clinched flanges on the hood, doors, tailgate and liftgate must be sealed with clinched flange sealer, if this is not already
applied.

Weld Components

Use a stripping disc to remove the cathodic primer on the inside and outside of the area to be welded. The stripped area
should be kept as small as possible, retaining as much of the cathodic primer as possible, taking care not to damage the zinc
coating.
Apply Welding Primer




NOTE: The welding primer must be stirred well or shaken before application.

Clean the repair area thoroughly, (silicone remover).

Apply welding primer evenly to all weld flanges, (old and new components).


NOTE: The welding primer must be allowed to dry before welding is carried out.
All weld beads must be ground down after all welding is completed, taking care not to weaken the material.
Any unevenness at the joint must be made good.
If necessary, spot weld missing weld studs into position.
The vehicle must be completely cleaned of sanding dust and metal swarf because of the danger of corrosion.
Clean and prime all internal areas and those to be sealed.

NOTE: The primer must be dry before sealing mastic or underbody protection is applied. Do not use thinners when
applying sealing mastic, (the mastic will not dry).

Partial Renewal

The procedure to follow when partially renewing components is the same as described in the section "Welded Components".

The main difference when components are partially, rather than completely renewed, concerns the preparation of butt or lap
joints.

When bodywork components are cut through, attention must be paid to the adequate removal of the paint and zinc
coatings on inner areas. This specially applies to areas which are difficult to access internally.
It is important for the weld quality that the inner area is bare metal. Zinc and paint residues in the weld area burn and
cause serious hole formation during welding.
If the zinc layer and the paint coating are not removed, the zinc and paint will burn during welding. The soot produced
prevents satisfactory cavity protection.
Procedure

The paint layer must be removed for a width of 30 mm from the line of the weld using a rotating tress wire brush.
This operation must be carried out on both the new and the old parts of the bodywork.
Depending on the bodywork component, a 10 mm width of the underlying zinc layer must also be removed along the
weld line. www.JagDocs.com

Body Repairs - Water Leaks - Water Leaks
Description and Operation

General Published: 11-May-2011

If water leaks occur after bodywork repairs, the cause can be established using the checks described below. A
systematic and logical procedure is required to locate water leaks. Before beginning extensive checks, a thorough visual
inspection must be carried out.
Visual Inspection
- The following characteristics may indicate existing leaks:
- Check the clearance and accurate fit of ancillary components such as the hood, tailgate, liftgate, doors, and so
on.
- Check for correct fit and possible damage to sealing elements such as blanking plugs, rubber door seals, and so
on.
- Check water drain holes for unhindered flow.
Various tests can be used to provide further information on possible leaks:
- Water test
- Washer test
- Road test
- Chalk (powder) test

Practical execution of tests and checks

Water test


NOTE: Never aim a jet of water directly at a rubber seal.

Carry out the water test with a second person present (in the passenger compartment).
Use variable washer nozzles (concentrated water jet to fine spray mist).
Start in the lower section and spray the whole area, working upwards in stages.

Washer test

Further tests can be carried out in the washer system.
Some leaks originate here, or only occur here.
The relevant passenger compartment should be checked using a torch during the wash procedure.
Road test

If no leaks are located during the tests above, road tests should be carried out on wet roads.
Road tests under various conditions:
- At various speeds.
- On various road surfaces (asphalt to cobbles).
- With loaded or unloaded vehicle.
- Driving through puddles (splash water).

Chalk test (powder test)

In this test, the clamping load and the bearing surface of the seal are checked.
Performing the test:
- Dust the door seal with powder or coat with chalk.
- Coat the bearing surface of the seal with a thin film of Vaseline.
- Slowly close the door and open it again.
- Check the width and continuity of the imprint on the door seal.

Other test equipment

Other equipment such as stethoscopes, UV lamps, special mirrors or ultrasound measuring instruments can be used to
locate leaks.

Rectifying the leak using recommended tools, auxiliary equipment and materials

Tools and auxiliary equipment:
- Dry, absorbent cloths
- Variable washer nozzle
- Torch, fluorescent tube
- Mirror
- Compressed air
- Seal lip installer
- Wet/dry vacuum cleaner
- Sealing compound compressor
- Remover for interior trim
- Cutter blade or pocket knife
- Wedge (wood or plastic)
- Hot air blower
- Special mirror for concealed leaks

- Air flow checker
- Sealing compound (tape and plastic compound)
- Multi-purpose sticker
- Clinched flange sealer
- Window sealing compound
- Water shield (PVC)
- Double-sided adhesive tape for water shield
- Methylated spirit (available from trade outlets)
- PU adhesive
- Silicone remover
- Tar remover

Water leaks according to mileage or running time
Increasing mileage has an effect on the problem of leaks in a vehicle. Possible influencing factors are:
Servicing and maintenance of seals:
- No maintenance, lack of maintenance or incorrect maintenance
- Using an incorrect agent
Damaged seals:
- As a result of aging, wear or incorrect handling/assembly.
Heavy soiling of the vehicle:
- Heavy soiling of a vehicle can seriously impair the function of water drainage channels in particular, and also of
rubber seals.
Age-related factors:
- Environmental factors
- UV radiation
- Extreme climatic conditions
Corrosion can have a serious impact on bodywork, in particular as a result of:
- Lightly or heavily rusted seal carriers
- Rusted body seal welds
- Perforation corrosion

Water leaks after body repairs
If a vehicle develops a leak after body repairs, the following points must be taken into consideration in particular:
The correct seating of ancillary components and their seals must be checked.
The correct alignment of doors/tailgate and liftgate must be checked. The associated seals must not be damaged and
must be installed correctly.
Check that panel seams are correctly sealed.
The correct seating of rubber grommets must be checked.
Directly-glazed windows must have correct and complete bonding.

Water drainage system

If a vehicle develops water leaks, then areas into which water is routed or drained should be checked first.

NOTE: In the case of a sliding or tilting roof, the external rubber seal and the lock actuator or latch mechanism
must be checked first of all.
- Check the water trap for leaks.
- Check the drain hoses for leaks and for correct connection to the water trap.
- Check the drainage system for unhindered flow, and blow out with compressed air if necessary.
- Check the external seal and the correct adjustment of the sliding roof.

Liftgate

Diagnosis:
- Ingress of water into rear headlining area and luggage area.
Cause:
- The leak problems of the tailgate and liftgate correspond to those of the doors.
- In addition to this, the area to be sealed is much bigger. The routing holes for cables and hoses must also be
sealed.
- The rubber grommets for the routing holes must be checked for damage and correct seating (fully unhooked).
- The mounting points of the liftgate hinges may leak.
Corrective action:
- Check the rubber grommets and renew if necessary.
- Check the hinge mounting points, and re-seal with sealing compound if necessary.
Forced air extraction

Diagnosis:
- Ingress of water into side luggage compartment area
Cause:
- The forced air extraction for the vehicle interior is located in the quarter panel lower extension.
- The rubber flap of the forced air extraction must be able to move freely.
Corrective action:
- Remove the forced air extraction.
- Check the seal area between the bodywork and housing, as well as the rubber flap.
- Renew seal if necessary.

Rear window
Diagnosis:
- Ingress of water into the luggage compartment area
Cause:
- Rear window leaking.
- Check for leak in the same way as for leaking windscreen.
