What You’ll Need
- White-Out (correction fluid) with a brush applicator
- Clean, dry cloth
- A flashlight (optional, for checking coverage)
Instructions
1. Clean the Area
Lightly wipe the surface around the pinhole with a clean, dry cloth to remove dust or residue.

Use the built-in brush to place a small drop of White-Out directly over the pinhole. Avoid over-applying — a thin, even coat works best.
3. Let It Dry
Allow the White-Out to dry completely. If the pinhole still leaks light, apply a second coat once the first has dried.
4. Check the Repair
Hold the fabric up to a light source to verify the pinhole is fully blocked. Reapply as needed for full coverage.

Why This Works
White-Out dries to an opaque, matte white finish that mimics the reflective coating of most blackout fabrics. It bonds well to the surface, blocks light effectively, and is a quick, no-tools-needed solution for field techs.
Pro Tips
– Works best on white or light-colored backout fabrics.
– Keep a small bottle in your tool bag for emergency repairs.
– Avoid using on textured or colored fabrics where the fix may be more visible.
