1. Confirm exterior oxidation
Wash and dry the lens. If haze or droplets are inside, the housing seal needs professional repair instead.
确认是外表氧化
清洗并擦干灯罩；若雾气或水珠在内部，应维修灯体密封。
2. Protect paint and trim
Work in shade on a cool surface. Mask all surrounding paint and follow the kit PPE and sanding sequence exactly.
保护车漆与饰条
在阴凉冷却表面操作，完整遮蔽周边车漆，严格按套装防护与砂纸顺序执行。
3. Restore evenly
Keep the surface lubricated if wet sanding is specified, use overlapping passes and never concentrate heat or pressure on one area.
均匀修复
若要求湿磨应保持润滑，采用重叠走向，不能在一点集中发热或施压。
4. Apply UV protection and cure
A clear UV-protection step is essential. Keep the lamp dry for the stated cure time and verify the night beam afterward.
恢复防紫外线并固化
最后必须恢复透明防紫外线层，按规定固化时间保持干燥，再在夜间检查光型。
