Which option correctly lists the key steps in a metal surface painting process?

• A. Primer only.
• B. Topcoat only.
• C. Welding prep.
• D. Surface preparation, primer, intermediate coats, topcoat, drying/curing, inspection and possible sanding between coats.

Answer: (D)

Painting metal effectively relies on a clean, layered approach: prepare, prime, build, finish, then inspect. Start with surface preparation to remove oil, grease, old paint, and rust, and roughen the surface so the coating can grip firmly. Next, apply a primer to promote adhesion and provide corrosion protection for bare metal. If a multi-coat system is specified, apply intermediate coats to build film thickness and add protection. Finish with a topcoat for color and UV and weather resistance. Between coats, lightly sand as needed to remove imperfections and ensure a smooth, even film, and allow each coat to dry or cure fully. Finally, inspect the completed finish for defects and touch up if necessary. Note that welding prep isn’t part of the painting sequence itself, though nearby welded areas should be cleaned during surface preparation to ensure good adhesion.
