Ignore the gaps in the bust; I'm in the process of filling them in. Using GE Silicone II (clear) Kitchen/Bath/Plumbing in a white tube with red markings. I already had it on hand. It's working beautifully. It's a little sticky so I keep a paper towel nearby to wipe my fingertips on. The antler is not attached -- I will wait 'til last to adhere it.
