Environmental Paint Damage Repair

SITUATION
Environmental issues can damage painted surfaces. Issues such as acid rain, industrial fallout, rail dust, bird droppings, and bugs can all damage the paint surface. Repair processes are in place to repair
damage caused by these issues.
Industrial fallout or rail dust issues typically occur when new vehicles have been transported by rail to a location, or when a vehicle is located near rail tracks for an extended period of time. Rail dust is comprised of heated iron particles from train brakes that, when airborne, will land on the horizontal surfaces of vehicles and imbed themselves into the paint surface.
Typical sanding and polishing techniques alone will not resolve the issue of rail dust. BMW, in cooperation with 3M, has developed a procedure for removing and correcting rail dust damage for the paint surface of a vehicle. Below are the process and product for removing and correcting rail dust damage.
PROCEDURE
The process below is for the removal of contamination and minor paint surface defects resulting from transportation and storage of new vehicles. Please be sure to use only BMW approved products when attempting to make a repair to the paint surface!
1. Wash and rinse the vehicle thoroughly, using BMW approved car wash soap*.
2. Check exterior surfaces for contaminants a rough or gritty feel, or use a white terry cloth towel to see if you get small snags of material on the surface.
3. Work contaminated areas with a 3M clay bar, using light pressure and car wash soap or 3Mtrade; Gloss Enhancer as a lubricant.
4. Rinse and dry the surface.
5. Knead the clay periodically to expose a new surface.
6. Polish the surface, using BMW approved polishing materials and techniques
Note:
Refer to the BMW Color system manual for approved polishing materials and proper techniques.
* Please see page two for a list of BMW approved materials.
