Correct Answer:
A. The surface must be clean and free of rust, oil, and grease; properly sanded to remove any old paint; dried completely before application; and primed with an appropriate primer.
Explanation:
- A. Correct: Proper surface preparation involves ensuring the surface is clean and free of contaminants such as rust, oil, and grease, adequately sanding to remove old paint, ensuring the surface is completely dry, and applying a suitable primer to ensure good paint adhesion and a smooth finish.
- B. Incorrect: Coating with wax, allowing surfaces to remain damp, and omitting primer are not standard practices for ensuring a good paint finish.
- C. Incorrect: Painting immediately after fabrication, allowing oily surfaces, and minimal cleaning are not recommended practices. A primer is usually necessary for proper adhesion and durability.
- D. Incorrect: High humidity can negatively affect paint application, primer is generally necessary, and applying only a single coat of paint is usually insufficient for a durable finish.
