PAINT Welded Panels

PAINT Welded Panels

Replacement Panels

Service panels are supplied with a cathodic primer coating as part of the panel protection, and in compliance with the vehicle’s Corrosion Warranty where applicable. DO NOT remove this primer before paint refinishing. In the event of localised surface damage or imperfections, ensure that the minimum of primer is removed during rectification work for effective repair.

Rectify damage by panel beating or straightening. To remove corrosion or paint runs on outer surfaces, abrade primer coat in the affected area as necessary using the following procedure:

1. Clean the panel using a solvent wipe. 2. Treat exposed areas of metal with an etch phosphate process. 3. Re-treat the affected area using either a Sectioned Panels separate acid-etch primer and two-pack When replacing part or sectioned panels, the basic surfacer, or an integrated etch primer/filler. procedure is the same as for welded panels described above, with the following variations:

Bolted Panels

Before fitting bolt-on panels, ensure that all mating and adjacent surfaces on the vehicle and replacement panel are free from damage and distortion. Rectify if necessary as described in this section, and apply preformed strip sealer where specified.

Remove all existing sealant using a scraper. This can be made easier by softening the sealant with 3M 8984 General Purpose Adhesive Cleaner or White Spirit before removal.

After the sealant has been removed, apply a suitable etch primer to all bare metal areas such as Berger Standox 1:1 Full Primer 405.0383.6 with 1:1 Activator 801.7997.5.

Where it is necessary to remove the door or bonnet [hood] hinges, ensure that the bare metal surfaces exposed are also etch primed.

1. Remove primer from the immediate vicinity of new and existing panel flanges, cleaning to a bright metal finish. 2. Where joints are to be spot welded, apply weld-through zinc rich primer to joint faces of both flanges. Make the spot welds while primer is still wet, or according to the manufacturer’s instructions. 3. Dress accessible weld seams. 4. Clean panel using solvent wipe. 5. Treat bare metal with an etch phosphate process. 6. Re-treat repaired areas.

• NOTE: It is not satisfactory to use
• weld-through, zinc rich primers in
• conjunction with arc or MIG welding.

1. Remove primer from both new and existing joint faces, cleaning to a bright metal finish. 2. Where an overlap joint with the existing panel is to be spot welded, apply weld-through, zinc rich primer to both joint faces and spot weld while the primer is still wet or according to the manufacturer’s instructions. 3. MIG weld butt joints where applicable. 4. Clean the panel with a solvent wipe. 5. Treat bare metal areas using an etch phosphate process. 6. Re-prime affected areas as necessary as for rectifying transit damage. 7. Treat the inner faces of lap or butt joints with a suitable cavity wax. See Sealing and corrosion protection.,
