Iodine, Ninhydrin, DFO, Silver Nitrate or physical developer. (Note: powders are generally insensitive to older fingerprints.)
Polyethylene, polypropylene, acetate and laminated paper surfaces.

Simulated leather and cling film.
Iodine, SPR, Cyanoacrylate and powders.
Untreated, bare metal surfaces— not metal surfaces that have been painted or lacquered.
SPR, powders, Cyanoacrylate/fluorescent dyes and powders.
