Prevent Rot Before It Starts.
Cobra Rods are a way to spot treat decay-prone areas such as log ends that are already coated with a finish. Dual-biocide of copper and borate prevents rot before it starts in highly-exposed logs and timbers.
Use on exterior logs and timbers exposed to high amounts of moisture.
Do NOT use on non-wood building materials, including fiber cement, vinyl, etc.
