Repainting damaged metal sheet

REPAINTING DAMAGED METAL SHEET

In the event of repairs being carried out on fixed or mobile parts, repair the defect in the metal and then proceed as described in PAINTING OF REPLACED FIXED METAL SHEET (complete cycle).

REPAINTING METAL SHEET WITH A SURFACE DEFECT

This cycle should be used in cases where the following anomalies occur:

• Water blistering
• Sagging
• Dulling
• Orange peel
• Dirt
• Transparency
• Roping
• Colour change
• Obvious touching-up
• Stripping
• Cissing
• Staining
• Roughness
• Chalking

The successive intervention phases relative to the surface painting operation of sheet metal are given below:

1. Preparation
2. Sanding (elimination of anomalies)
3. Dulling with scotch brite across the entire surface
4. Masking
5. Application of paints (paint and varnish)

• Wash the affected areas, dry sand, clean with a cloth soaked in a silicone-proof product and dry carefully.
• Sand to eliminate the anomalies in the sheet metal.
• Dull the entire panel with brite.
• Mask the areas surrounding the sanded surfaces and suitably cover the remaining part of the vehicle.
• Blow-off with compressed air and clean the surfaces with a tack-rag.
• Prepare and apply the paints (paint and varnish). For the appropriate flash-period between coats consult the manufacturer's technical charts.

RESTORATION OF METAL SHEET WITHOUT REPAINTING (DENT REMOVAL)

This procedure enables small dents to be removed from the bodywork using suitable tools and avoids surfacing and painting therefore maintaining the initial characteristics of the metal sheet.
