It has also been used to lift powder developed prints and or other impressions from human skin

I have used Mikrosil to lift dried blood prints off a wooden table by making use of silicon treated paper. The print is photographed using oblique lighting. The print itself is obviously not lifted but only the "contours". This was done during an experiment and was under controlled circumstances.

Mikrosil is a valuable tool for lifting latent prints developed with powders. I have also had success lifting SPR prints with Mikrosil. It is generally used on "difficult" non-porous surfaces such as anything textured (dashboard, back side of rearview mirrors, etc.) and curved surfaces such as a doorknob or the underside of car door handles where tape can be cumbersome. Of course you would want to use a color of Mikrosil that contrasts with the color of powder used.

Liquid rubber-like lifting of various types of latent impressions have been documented over the years.
In 1978, Jon Howington authored an article titled, "Thiokol Rubber Casting of Impressions in Dust and Soft Surfaces," (ID News 28:3, March 1978).
In 1987, Ernie Hamm authored an article about similar materials titled, "THE CUSTOM-MADE RUBBER LIFTER," (JFI 37:7, July 1987).
In 1998, Andre Bay authored an article titled, "Additional Use for MikrosilTM Casting Material" wherein he mentions processing latent impressions on candles, soap, grease, etc. (JFI 48:2, March/April 1998).
There have also been articles about using less exotic silicon rubber substitutes such as various glues.

Has anyone used Mikrosil for casting/lifting latents? If so what type of surface, what process was used?
