Back-To-Basics: Corrosion

Posted on 14 November 2018 | Share:

Sometimes going back-to-basics can make the difference between a quality repair and a failed repair. When repairing and refinishing, corrosion can be avoided by taking proper steps to ensure a clean metal surface.

Corrosion may not be visible by looking at the refinished surface unless, in most cases, it causes the paint to blister or raise. Some ways to help avoid corrosion:

  • Always wear gloves and follow paint maker instructions for proper metal treatments and primers during the refinishing process. The oil from bare hands touching the metal before refinishing can interfere with paint and primer.
  • Drill all necessary holes before the refinishing process and clean the holes of burrs and flakes to ensure that dissimilar metals do not come in contact during the refinishing process. This type of corrosion is called galvanic corrosion.
  • Clean welds thoroughly and apply corrosion protection or primers according to the paint makers recommendations.
  • Inspect filters around the spray booth for moisture. Filters may need to be emptied and/or replaced, it is imperative that there is no water in the air supply.
  • Improper drying or cleaning of the bare metal areas. Clean the vehicle thoroughly following paint makers instructions on what product to use. Make sure there are no sources of moisture on or around the vehicle before refinishing.

By concentrating on the basics, you can avoid many of the problems that would otherwise prevent complete, safe, and quality repairs.
