Description and Operation
Body Pre-treatment, Painting and Sealing
PVC Coated Underside

The body is pre-treated to ensure high resistance to corrosion and stone chip dama ge. Prior to the first major pre-treatment process, the body shell is high-pressure washed to remove any metal dust and residual oil.
The first major pre-treatment process consists of phosphate and electro-paint deposition, which together with zinc coating,
forms the basis of the corrosion protection. This process includes high pressure knock-off, alkali de-greasing, zinc phosphate
conversion of body steel (dissolving iron and coating with zinc phosphate crystals), trivalent chrome rinsing and
demineralized water rinsing, seal ing all chemicals and impurities.
Both dip and spray techniques are employed and the bodies are submerged to the waistline during the first and third rinses
of the main phosphate clean. Chemical strengths and soluti on temperatures are continuously monitored and accurately
controlled throughout the process.
An 80% water primer is then cathodic elec tro-deposition applied to the thoroughly cleansed bodies in a uniform 'sag-free'
film 18 to 32 micron thick. Optimum durabi lity of the electroprimer is achieved by finally curing in a stoving oven at 165 °C
for a period of 20 minutes.
All underbody seams of the fully primed bo dies are then manually sealed, to prevent water and dust ingress into the vehicle
and to enhance corrosion protection.
An 800 to 1000 g/m2 PVC coating is semi-automatic airless sp ray applied to the underside of the main floor panels, trunk
floor and rear wheel arches (ref. illustration above).
The upper panels of primed and external ly sealed bodyshells are next lightly scuffed to remove imperfections and a PVC
coating is applied to all internal seams by an airless spray technique. A PVC bead seal is also applied to the doors, hood and
trunk clinch joints.
Following anti-corrosion, sealing and primin g treatment, the bodies enter the first stage of 'cosmetic' painting. This consists
of the application of two coats of a highly chip resistant po lyester surfacer, employing high voltage electrostatic 'spinning
bells', to achieve a final film thickness of 35 to 50 micron. Between surfacer coats, a polyurethane coat is automatically
applied to the sills to impart even greater resistance to stone chipping.
All interior panels are then painted us ing a color keyed sealer, wet-on-wet wi th a surfacer material, after which the
bodyshells are stoved at 160 °C for a period of 20 minutes. Further protection agai nst corrosion is provided by a medium
solids black pigmented wax which is airless spray applied to vehicle undersides.
Wax Injected Box Sections
Critical body box-sections are si milarly protected by spray injecting a high solids wax. This is then re-flowed at 70 to 90 °C
to achieve optimum seam/joint penetratio n and form a resilient and durable internal coating (ref. illustration above).
After full wet sanding, rinsing and drying to provide a good su bstrate, a color-keyed semi-matt sealer co at is applied using
electrostatic bells to achieve a film build of 25 to 35 micron . The bodies are then stoved for a further 20 minutes at a
temperature of 145 °C and subjected to a local 'seek-and-find' de -nib operation prior to the final two coat process. The final
top coat finish is achieved by using poly ester base coat colors and an acrylic sag resistant clear coat. This clear over base
(COB) process produces a high gloss, durabl e paint finish with a film thickness of 50 to 65 micron, which is finally cured at a
temperature of 135°C for 20 minutes.
The Munsell three dimensional system of color management is em ployed to achieve highly accurate control of vehicle colors.
This system ensures that paint pigmentations are accurately maintained and facilitates vigorous final checking of finished
vehicles for color match. The hu e of individual panels such as trunk lids, doors and hoods is in some instances adjusted to
offset the effects of differing light angles. Where applicable, coachlines are manually applied and radiant heat cured on the
completed and valeted vehicle prior to hand spray applic ation of a protective wax coat.
Introduction
All repairs, whether structural or cosmetic must return the vehicle to the original manufactured condition with regard to
occupant safety, dimensional accuracy, fi nish and corrosion protection, and ensure continuation of the Paint Surface and
Corrosion warranty where applicable.
Similarly, repaired vehicles must be fu lly checked, and where appropriate reset, with regard to steering, suspension,
braking, and occupant restraint systems.

Paint
The inhalation of sprays, fumes, or dust during paint application or sanding processes should always be avoided. Ensure
that there is efficient ventilation / extrac tion at all times. Paint spraying should be confined as far as possible to spray
booths. Personnel with a history of asth ma should not be employed in any process involving the use of isocyanates.
Operators working in a spray booth where isocyanate material is present must use air-fed breathing equipment with air
supplied to the visor at the re commended pressure and filtered to remove oil, water, and fumes. Operators involved in
handling mixing or spraying should wear protective clothing including gloves and goggles, to avoid skin and eye contact.
Particle masks or canister type respir atosr should be worn when sanding.
Applied Heat
When welding, flame cutting, brazing etc, the operator shou ld use as appropriate, goggles, mask / fume extractor and
flameproof protective clothing. It is especially important when working with polyurethane compounds to use air-fed
breathing equipment. Appropriat e fire fighting equipment and personnel trai ned in its use must always be available.
Metal Repair
Appropriate eye and hand protection should be worn when sanding, drilling, cutting, chiselling, flatting or welding. Face
masks or air-fed visors should also be wo rn when sanding or flatting either body solder or fillers. On completion of a
soldering operation, swarf must be re moved from the work area and the operat or must wash his hands thoroughly.
GENERAL REPAIR NOTES
The following advice should be noted before any repair work is carried out.
Disconnect the vehicle battery gr ound lead (disconnect the alternator where electric welding is used) and take note of the
reconnection procedures as detailed in 86.15.15.
Where structural parts are straightened or renewed, a body alignment / straightening jig must be used. The application of
heat, especially excessive heat, reduces the strength of steels, where appropriate therefore, structural sections should be
straightened by cold processes.
Repairs may only be carried out successful ly, and any warranties protected, if genuine Jaguar replacement parts and Jaguar
approved materials are used.
The correct tools, procedures and facilities must always be us ed. The quality of the work must not be compromised by using
inappropriate methods or equipment.
All trim and electrical components in the locality of the repair must be removed or disconnected prior to panel removal /
replacement; this is especially important where hollow sectio ns may contain harnesses, tubes or foam, see section A4.3.5.
WARNING: DO NOT WORK IN THE VICINITY OF A LIVE AIR BAG, REMOVE IT COMPLETELY. READ WORKING
PRACTICES AIR BAG, SECTION 20. ANY SEAT BELT WHICH HAS BEEN WORN IN AN ACCIDENT MUST BE RENEWED.
CAUTION: Electric arc welding should not be used on Jaguar vehicles. The high voltages produced by this process will
cause irreparable damage to the electric al control and microprocessor systems.
The following welding and gas processes are the only ones recommended by Jaguar Cars Ltd.
Welding and Gas Processes
Resistance spot welding, MIG welding and all gas processes may only be carried out on bare, unpainted or unplated metal.
The flanges of panels to be welded toge ther, must be clean, corrosion free and tr eated as appropriate, with either weld-
through primer or inter-weld sealer. Only materials and processes specified in the 'Body Sealing and Preservation Manual'
should be used in the relevant application areas detailed in this section. Refer to 'Zinc Coated Panels' Section

BODY ALIGNMENT
The Body Dimensions Plan, and Body Dimensions Side View, provide specified BIW dimensions to facilitate damage
assessment and location of replacemen t parts. These dimensions must be strictly applied when used for damage
assessment, component location or post repair verification.
• NOTE: The right-hand side is always looking towards the front, from the rear of the vehicle.
The nominated plan view master datums are on the right-hand side of the body with the left-hand datums dimensioned
from them. Right-hand datums must therefore be known to be correct before any other cross-car dimensions are checked.
Datum location, Example
The Front Master Datum (front crossmember rear mounting at the inner face of the main floor RH longitudinal) is nominally
359,5mm to the right-hand side of the body center line. The LH side fron t datum is measured 717,0 / 721,0mm from the
RH. Refer to the Body Dimensions Plan.
