Which statement correctly describes wet nonaqueous developer?

• A. Very portable (spray can)
• B. Coating is translucent and provides poor contrast
• C. Indications for water washable systems are dim and blurred
• D. Indications weaken and become diffused after time

Answer: (A)

Wet nonaqueous developer is a solvent-based liquid used with penetrants, and it is typically applied as a film from a spray can. That spray-can format makes it highly portable for field use, since you can carry it easily and apply it without any water or additional equipment. The film it leaves is meant to be opaque and provide strong contrast with any detected indications, so a translucent coating with poor contrast would not describe how this developer is used. Statements about being tied to water-washable systems or about indications weakening and diffusing after time don’t fit how wet nonaqueous developer behaves—those describe other system types or unrealistic results.
