Loose paint, bubbling and discolouration of the paint film, especially around body fittings, panel edges and seams.
Corrosion of the metal substrate, resulting in loss of adhesion of the paint. This is frequently caused by:
- Exposure of bare metal surfaces by accidental damage, or by leaving drilled holes untreated.
- Exposure of bare metal surfaces due to destruction of the paint film by contamination.
- Ensure that all metal surfaces are treated with the correct metal treatment fluids and etch primer prior to painting.
- Repair any damage to the paint film as soon as possible. Always treat any newly exposed metal edges immediately.
Strip the paint from the affected area down to the bare metal, remove all existing corrosion, treat the surface with the correct metal treatment fluids and etch primer, and repaint.
