Visible penetrant may be applied by which methods?

• A. Rubbing
• B. Brushing, spraying, and dipping
• C. Painting
• D. Wiping

Answer: (B)

Visible penetrant is applied by brushing, spraying, and dipping because these methods provide controlled, uniform coverage that allows penetrant to enter surface-breaking defects. Brushing lets you apply penetrant to specific areas and work it into features; spraying offers an even coat over complex shapes and larger areas; dipping immerses the entire part for complete coverage, which is especially helpful for small parts or parts with intricate geometry. Rubbing or wiping tends to remove or smear penetrant and produce uneven results, and painting isn’t used here because it doesn’t guarantee proper penetration or compatibility with the inspection process.
