2. REPAIR INSTRUCTIONS FOR COLORED PP BUMPER
NOTE:
All PP bumpers are provided with a grained surface, and if the surface is damaged, it cannot normally be re-
stored to its former condition. Damage limited to shallow scratches that cause only a change in the lustre of
the base material or coating, can be almost fully restored. Before repairing a damaged area, explain this point
to the customer and get an understanding about the matter. Repair methods are outlined below, based on a
classification of the extent of damage.
1) Minor damage causing only a change in the lustre of the bumper due to a light touch
Almost restorable.
