The lifting of dusty prints that are visible in dust can be accomplished by using a polyvinyl, such as those found in the extruder guns for $100, or the blue gel Elmer's Glue. Allow the glue to set completely and with as few air bubbles as possible. Best to practice with these methods. And used only after the proper photographic documentation.
Webservant Note: Microsil, liquid latex/rubber materials and similar methods have also been published in the JFI, etc.

The first technique is photography with a strong and precise oblique light source in an otherwise dark room. Use multiple angles and directions, as detail may show up in one photograph that doesn't show up in another. If you set up a high quality digital camera on a tripod to capture the images, it would be possible to later easily combine the good detail from several different lighting angles in a program like Photoshop.
There are several methods for lifting, which include an electrostatic dust lift or black gel-lifter. I would be careful with the gel lift because I have heard that the dust may be immediately absorbed into the lift and the print can dissapear quicker than you had hoped. The electrostatic lift can be photographed with special lighting techniques to produce good results. I would recommend reading up further on this if you have not already done so.
There are also some spray developers for dust, but I am not very familiar with them... they are used mostly for the development of shoe impressions that contain dirt or earth, as they react with the minerals and contaminants I believe.
Good luck in your photography endeavors! I still think that is your best bet.

Is there a good procedure for lifting latent prints from the painted metal surface of a dusty car? The dust is not very deep and the print is less than 24 hours old. Thanks.
