Good morning via the "Detail," a weekly e-mail newsletter that greets latent print examiners around the globe every Monday morning. The purpose of the Detail is to help keep you informed of the current state of affairs in the latent print community, to provide an avenue to circulate original fingerprint-related articles, and to announce important events as they happen in our field.

Last week we reviewed a recent radio program on fingerprints.  This week, I am proud to bring you another AWESOME example of why the Detail was created.

I had the pleasure of meeting the Editor of the Texas Division IAI, Ed McKinstry at the Parent Body IAI conference in Las Vegas.  We have been in touch since then, so it was no surprise to get a phone call from Ed a few weeks ago.  He was researching a unique idea to see if it was indeed 'new', or if I had heard of anyone experimenting with the concept.  I had not.

The Weekly Detail was created to pass on new and unique fingerprint related news and useful information.  I can think of no better example of this than Ed's GREAT idea, followed by distribution in the Detail.  Thank you, Ed, for this week's excellent submission!:

Rain-X Today Keeps the Residue Away
By: Edward A. McKinstry

We all know that keeping the glass in your glue tank clean is a necessary chore, but one I find myself doing a bit too often. I was recently thinking about this problem as I was cleaning the CA residue off the glass. What could I do to get a longer hiatus between cleanings? Using my “critical thinking” skills I realized if there was a way to reduce or eliminate the moisture that accumulates on the glass generated from the hot water in the tank then I would be able to get extended use out of my glue tank before cleaning. I came up with the idea of Rain-X. Rain-X is a silicone based glass treatment that seals the microscopic pores of the glass creating a hydrophobic (water-repelling) surface. 

I have a 100 gallon tank that is all wood except for two glass windows. After cleaning the glass in my tank to remove all residue, I applied two treatments of Rain-X to one glass pane in my tank leaving the other untreated. I did two normal fuming sessions with evidence. There was no accumulation of CA residue on the Rain-X side while the untreated side already had significant residue build up. I was very pleased with the results, and just to see how much the Rain-X could repel, I placed 8 cups of very hot water in the tank for twenty minutes, used five times more glue than normal on the hot plate and left it overnight. There was no accumulation of CA residue on the Rain-X pain and the untreated pain was to the point of cleaning. I have used my large fuming tank on three more occasions and have yet to see any residue buildup on the treated side, while the untreated side is completely glazed over.

My next test was with a 10-gallon size aquarium. The glass was cleaned and I applied Rain-X to half of the tank. I placed 100ml of hot water in the center of the chamber and placed a Hard Evidence glue pouch to the inside of the lid. At the end of 15 minutes, the two untreated panes were already coated with CA residue while the Rain-X treated sides were still clear of any residue. I let the tank fume for an hour after which the two untreated sides were completely covered in CA residue while the Rain-X treated sides were still completely clear of any residue. 

I have yet to determine just how long an application of Rain-X will keep my tank clean, but experiments are continuing. I wanted to go ahead and get this information ‘out there’ and perhaps save a little bit of cleaning time and effort for a lot of people. The results of experimentation are being published in the Texas Division, IAI and possibly the Journal of Forensic Identification.  But hopefully in the mean time, you can save yourself a few additional cleanings you would have otherwise had to do.

See what I mean!!  Just think... today, across the globe, fingerprint examiners will be at Wal-Mart during lunch, and this afternoon they will be getting out the straight razor and cleaning that glass (really well) for what hopefully turns out to be a much longer time of use than before.  Well, OK... maybe there will be those few who actually try to turn in a purchase order or a receipt to reimburse them a few bucks.  Look at it this way... who doesn't have to clean as often now!?!  I'm just going to go buy my bottle.  Besides, then I can squirt some on my car windshield and not feel guilty.  :)

Have you found anything to work better than Vaseline or Rain-X on your glue tank glass?  Have you been using Rain-X?  Drop me a note (kaseywertheim@aol.com) or log on to the message board to discuss this or other fingerprint related matters: 
And as usual, the onin.com forum (http://onin.com/fp/wwwbd/) is also available for more formal latent print-related discussions.


It looks like the Funny Fingerprint Find section will be here for a while... but I will only stretch it out as long as there are submissions, so keep them coming!  This week's Funny Fingerprint Find comes from Steve Everist... Thanks, Steve!
