Most often a problem of faintly glimmering lights bothers owners of the cars produced in the end of 1990-s. The cause lies in the plastic bodies of the front lights. Despite the protective layer, the front lights are still exposed to impacts of small pebbles, water and heat. As a result of micro-scratches and chips, the light becomes dim and cannot be properly diffused. The matter is resolved by polishing of lights. Lights polishing stages are similar to the stages of the car body deep polishing, however, they demand more attention and care.
