Dykem "Cross-check" torque seal is your friend.
If paint seal is broken the bolt/nut has moved and lost torque.
Saved my bacon a few times after 30 years in the air.
Used extensively in aviation maintenance on critical components.
Helped catch trouble before it happened in the Cobra as well.
It's high temp and resistant to
oil/fuel.
