flaws in metals and castings that are not visible to the naked eye.

Before Spraying: Shake can at least 45 seconds AFTER the mixing ball begins to rattle. Shake the can occasionally during use.

Step 1 – PRECLEAN (Grey): It is essential to ensure that the part/area to be tested is clean, dry and free from all surface contamination (e.g. grease, oil, rust and paint). Spray the area to be inspected and wipe thoroughly with cloth. Allow clean surface to dry.

Step 2 – PENETRANT (Red): Spray Penetrant dye over the cleaned area that is to be inspected. Allow Penetrant to dwell for 10 minutes. Dwell time should be extended in
extremely cold conditions.

Step 3 – REMOVER (Blue): Allow excess Penetrant to drain. Wipe over inspected surface with a dry cloth. Then spray Remover on another cloth and wipe surface to remove
excess Penetrant. Allow surface to dry before using Developer.

Step 4 – DEVELOPER (White): Spray a light coat of the Developer over the area to be inspected, avoiding a heavy film. Leave developer to dry and inspect parts for flaws after
2-3 minutes. If very fine flaws are suspected, the parts should be re-inspected after 20 minutes.
