Which term describes preparing a surface before applying a repair to prevent corrosion spread?

• A. Surface prep and touch up
• B. Surface coating only
• C. Final inspection
• D. Surface cleaning only

Answer: (A)

Surface preparation before applying a repair focuses on getting the surface ready to bond and seal so corrosion can’t spread under the repair. This means removing oils, dirt, rust, and any old coatings, and often abrading or profiling the surface to improve adhesion. The touch up part covers applying the protective coating to small areas after the repair to restore a continuous barrier. Together, surface prep and touch up describe the full process needed to prevent further corrosion at the repair site. The other options don’t fit because cleaning alone stops at removing contaminants, coating alone assumes prep is already done, and final inspection is a check performed after the work, not the preparation step.
