Just curious what sort of UV lights folks are using?
My son being a mechanic uses an ultra violet light to detect leaks in the coolant system in the fleet vehicles he services. He has a pretty good knowledge of what works and what doesn't. He turned me on (sorry for the pun) to a little UL flashlight, BOLDER, by ANKER, $23 on Amazon
For those of you that are on a budget or, like me, who feel specialized stamp stuff is too expensive. This is a pretty good deal. It's small, easy to handle and short wave. Works on all the stamps I have and is good detecting grills, embossments...
Just sayin!*** Moved by Staff to a more appropriate forum. ***
