Even though the caulk gun wasn't the right size, I did run up to check out the lotus petals. They look great! I also realized that, tomorrow, I'll bring some webbing and a harness. It's much smaller up there than on the Enlightenment Stupa, so crawling around to caulk the petals will be better with some form of security. I also walked around and looked at the Stupa and the smaller Stupas as well, and for the most part, they look good. Some areas to repair, but not anything major. The Auspicious Manifold Doors Stupa really is the biggest job out here...
