  • Paint Problems - RAIL DUST

    RAIL DUST

    Small rust colored bumps or specks in the surface of the paint film.

    CAUSE

    When vehicles are transported from the manufacturer by rail, iron dust particles created by friction between train wheels and the track settle on the finish. When exposed to oxygen and moisture, this dust corrodes and become embedded in the finish.

    REPAIR

    Use a 30x magnifying glass to verify the presence of rail dust damage. Use caution when accessing damage to prevent scratching the paint surface.

    Wash the vehicle with soap and water, rinse and dry.

    Solvent clean with appropriate surface cleaner.

    Use an acid based rail dust remover following manufacturer's directions.

    Rinse with cold water then inspect the affected area to see if all particles have been removed. Repeat step #3 if necessary.

    If the finish is pitted, sand with 1200 or finer grit sandpaper to remove damage, then compound and polish to restore gloss.*

    Or, sand and refinish.

    PREVENTION

    Unfortunately, since this type of damage usually occurs during shipment or storage, little can be done to prevent its occurrence.

    *When sanding and buffing a basecoat/clearcoat finish, a minimum film thickness of the clearcoat (2 mils) is required to maintain adequate ultraviolet protection. If correcting the damage will result in removing more than .5 mils, refinishing is recommended.
