Superglue Fuming. The CA fumes bond to the surfaces of the items and latent print visualization is, hopefully, achieved. (1999) reported a case in which latent fingermarks were developed inside a vehicle by cyanoacrylate fuming method. The role of the fingerprint material in the process, leading to formation of methyl cyanoacrylate polymer at the site of the fingerprint, remains to be established.
