Our new Lightning Powder Aerosol Fingerprint Powder uses the same powder that you have come to trust over the years, but in a convenient, controlled aerosol spray. The cleanest way to apply powder for processing suspected fingerprints. Noted for its coal-black hue and property of adhering to the latent print, but not to the background surface, Lightning® Black Powder has been used by latent print examiners and crime scene technicians for over 70 years. It is recommended for most general dusting situations.
