To perform a structurally effective housing repair, it is essential to follow a precise procedure: thoroughly clean the damaged area, prepare the welding grooves using the appropriate scraper, secure the broken sections with pre-cut staples, and proceed with welding using a plastic filler rod compatible with the material of the component being repaired.
Lens repair is possible only when the damage is located in areas that are not directly visible and are not crossed by the light beam, such as sections covered by the bumper or bonnet. If the damage affects the front optical area, complete headlight replacement is required.
To achieve an optimal result, the crack must be:
- Properly prepared through cleaning and groove preparation while limiting heat input during the welding process
- The molten filler rod must be firmly pressed into the heated plastic, ensuring proper fusion and preventing excessive formation of air bubbles
The final stage involves orbital sanding using polyurethane mesh abrasives with progressively finer grits, followed by the application of a clear coat. This ensures a completely watertight repair and an aesthetically pleasing finish
