What term describes a temporary protection applied to surfaces where the coating has been damaged or removed?

• A. Primer
• B. Compound
• C. Sealant
• D. Wax

Answer: (B)

When a coating is damaged or removed, you need something that can fill and smooth the exposed area to restore a surface you can safely repaint over. A compound fits that role because it’s a malleable filler used to repair and level irregularities, creating a protective barrier and a uniform surface until a permanent repair or recoating is done. Primer, sealant, and wax each serve different purposes—primer is an adhesion base for paint, sealant bonds gaps and joints, and wax provides a surface protection on finished coatings—not suitable for filling damaged areas or providing the temporary patch the surface needs.
