When should Blitz™ fluorescent magnetic powders be used?.The choice is dependent on the surfaces which need to be dusted. Surfaces such as plastic bags or shiny magazine covers first should be fumed with Hard Evidence? pouches or Hard Evidence™ Liquid Glue and then dusted with Blitz™ fluorescent magnetic powder.

Other smooth surfaces, like vehicles and glass, can be fumed first and then dusted with Redwop™ fluorescent powder. If fuming is not practical, dusting with Redwop™ fluorescent powder alone may yield results with a forensic light.

Blitz-Green™ magnetic fluorescent powder fluoresces well when viewed under the wavelengths listed below and with the lower nanometers also. It adheres well to most glossy papers and smooth plastic items. Blitz-Green™ magnetic fluorescent powder is particularly sensitive to Ultraviolet wavelengths. Magnetic fluorescent powder fluoresces strongly when viewed under 450 nm, 485 nm, 525 nm, 530 nm and 570 nm wavelengths of light
