The restoration technique for corroded aluminium panels differs from company to company. Generally, it involves removing surface dust and grit, removing the surface corrosion product and finally applying a surface protector.
For coating issues that don’t involve etching into the bare metal, abrasion technique (grinding and polishing) may be tested on a small area to determine the most effective corrective actions. If a new coating is needed after cleaning and fine polishing, a primer may be required to prepare the surface.
For anodised coatings, re-anodising is an option. However, before re-anodising can be done, the existing anodised layer must be removed. Any paint or lacquer applied over the anodised surface must first be mechanically or chemically stripped. The anodising itself is removed using an etching solution. Afterward, any scratches, dents, or pitting should be smoothed out. Finally, the surface should be polished or ground to a smooth finish before applying a new anodised layer.
