The undisturbed area at the bottom right of the mullion is an old epoxy repair, around which the wood continued to rot. To ensure that won't happen again, Stahl injects a borate wood preservative into holes drilled halfway into the wood. Sealed over with epoxy, the borate penetrates the wood, minimizing the chance of future decay.
