Discovered a trick for reading those blurry part numbers on old boards

Been battling faded or scratched part numbers on some 20 year old circuit boards from a King Air. Tried different lighting, magnifiers, even my phone camera zoom. Nothing worked. Then a guy at the hangar in Wichita told me to wet the surface with a drop of isopropyl alcohol and hit it with a bright flashlight at an angle. Could read the numbers clear as day after that. Anyone else got a weird trick for identifying components when the markings are gone?

Ngl, is this really that critical for a King Air avionics bench troubleshooting?

Man, I feel you on that. Sometimes people get way too caught up in the little stuff.
