Removing calipers...How can I seal the line to prevent fluid loss

Going to remove my brake calipers to repaint them.
How can I seal the banjo ends of the lines to prevent fluid loss and a big mess?

As long as you don't open the cap on the master cylinder, the fluid should not poor out. You'll maybe get a few drips.

Has your brake fluid ever been replaced? If not, its time.
