We would recommend using Boracare. Apply only to bare wood or to wood surfaces where an intact water repellent or finish is not present. For preventative measures, you will use 5 gallons of very hot water with 1 gallon of Boracare. You can either paint this on or spray it on. Once the product dries, you can do whatever you wanted to do with the fence. We would recommend not spraying when anyone is around. It normally dries within 2-3 hours. Please let us know if you have any additional questions.
