    Have heard about doing it, people use it to discover overspray etc. What am I looking for? How do I know if something has been altered? The more information the better, pics certainly appreciated.

    Old nitro glows kind of a snot green, but the main thing is that it should be pretty uniform. THe backlight will show off differences in the age of the finish. Hard to explain till you've seen it.

    Google to see if there are any images. The blacklight shows any overlap or inconsistencies.

    that's a good thread on the subject. here's another:

    http://www.lespaulforum.com/forum/showthread.php?t=113937

    from that thread, this makes it the most obvious:

    "some were asking about pics from a blacklight test.

    A bandmate has a guitar with a cracked and repaired headstock and today I tried to take some pics in a blacklight situation.

    First a pic of the repaired area with normal light (neon):

    I have a vintage (hihi) - Made in USA - Sylvania 47 inch long blacklight in my rehearsal room.
    Today I switched the blacklight on, let it power up for some minutes, took the guitar on a stand, used a tripod for my camera, switched off the normal lights so it was totally dark and took the pic with 16 seconds of exposure.

    Here's the result:

    Well, the repaired area (the new finish) is clearly visible in the pic, the different hue/color is popping out. Hope this helped a bit."
