Troubleshooting a 737NG pitot static leak took me all day Tuesday

We had a 737NG come in with a pitot static leak that drove me nuts. Spent from 7 AM to 4 PM chasing it, checked every fitting and line twice. Turned out it was a tiny crack in the static port union, barely visible without a magnifier. I mean, I must have removed that panel three times and finally used soap solution on the whole run. Has anyone else had a leak that hid that well, or am I just losing my touch?

Soap solution always finds what the eyes miss, good trick to remember.

Is it really that deep, or just bubbles?
