Ink with acid etch might work but I've not see any of that since I was building titan sites around EAFB in 1960-61.

Or you can find one marked "permanent" which has solvents that can penetrate the lube film. This might be a place for candle smoke if it wasn't such a bitch to re-assemble for testing, I usually smoke rifle actions to get a good start on bedding them into the wood.

And its un-tough enough to show the contact pattern pretty easily. That I can get at Wallies. No clue if they'll be open tom. though as tom. is Independence day on this side of the pond.
