How would you suggest handling checks that were processed with ninhydrin 35 years ago, and now you need to bring the prints back a bit because they've faded over time?
Any ideas? Reapply ninhydrin? Zinc chloride? Indanedione?

Hi Ernie,
I sent you an e-mail via this web site, however I'm not sure if it went through. Can you contact me at my personal e-mail address?
