Here's a close up of the worst damage. You can see the screws had rusted, and that water had been running down behind the relief when it was mounted on the Stupa. This is the result of a break in the caulk seal, which is something we must be vigilant of in the future to prevent any further damage. Ani Sherab doesn't think this is really all that bad, but wants to teach us how to repair it while she's here. : ) We're all eager to learn...
