Forensic DNA marking systems

Due to an increase in the price of copper there has been an increase
in thefts of metal from roofs and gutters of historic buildings, not
least churches.  Forensic marking, consisting of a solution with a
unique coded identification, sometimes called "DNA-paint", has been
tested by some churches.  The forensic marking paint is used to
detect and identify stolen metal and to prevent theft.  Use on
artifacts has also been suggested.

We are in the process of gathering information on issues to do with
the paints' effects in the long term.  For instance, possible
corrosive effects, reversibility etc.  The question we would like to
ask is: has anyone used this kind of paint or have experience from
its use to share?  Also, any information or reference to research to
do with the subject would be greatly appreciated.
