In addition to that, I have also heard that the 'ghost' in the cast iron can be changed prior to decking so that the acid method is ineffective. I will not post that here for obvious reasons but am told that this works similar to how it is done on guns. This 'impact' method somehow changes the metalurgy of the cast iron and makes what was, now illegable.

Like anything else in this world, what ever man creats as a method of detection, an unhonest person will counter.
