We (foolishly!) left our glass citronella torches outside over our cold Missouri winter and one of them cracked and leaked oil. I am wanting to save it by repairing it because it has been discontinued and cannot be replaced. My husband, a very handy man, is stumped. Because the oil leaked out of the crack, glue will not adhere. He's considered a fiberglass patch, but thinks that is also unlikely to work. Any suggestions? I hate to have one mismatched torch!
