I was bonding the bottom of my acrylic tank (24"x12"x12") 1/4" size and one of the acupuncture needle tip broke inside the seam. There is no way for me to reach it with plyers to remove it...such a pain. There doesnt seem to be any air gaps at all surronding the tip of the needle, it's all glassy. Am I screwed? Will it have an impact in the long with the seam? What can I do?
