Torque seal pen trick that saved my tail on a B-737 brake job

Last Tuesday I was doing a wheel and brake swap on a 737 that came in with a hot brake write-up. You know how it is, all those bolts on the main gear axle need precise torque and then you gotta mark them. I was using a little paintbrush and a bottle of torque seal like I always did. But I kept dropping the brush into the wheel well and getting seal all over my fingers. After the third time fishing it out, I grabbed a cheap blue paint pen from my toolbox instead. Just scribbled a line across each bolt head and the flange. Worked way cleaner, dried fast, and I could even see the line from a weird angle without a flashlight. Has anyone else switched to paint pens for this stuff, or am I late to the party?

Jumped on that trick years ago and never looked back. The paint pen line holds up way better than brushed on seal, especially when you're working in tight spots or bad light. Saved me from second guessing myself more times than I can count on landing gear jobs.

Respect that, man. Totally get the struggle in those tight spots.
