When I try to take fingerprints, they fade very quickly, before I can put the tape on them. Or, maybe, I'm doing it wrong? Any advice?

You aren't doing anything wrong littledog, that one and the blood stains were a ridiculous task that I had to do over and over before I got it right.

Hi littldog

If you can get the tape on the right place it does not matter if you can't see them anymore, you can still pick them up.

I just quickly hit all around the area that I saw the print until the tape grabs it.
