The sprinkler near the garage door keeps the bottom panel(s) wetter than otherwise in South Florida's semi-topical climate. It is time to replace the door panels once again. They are no longer made of the world's best lumber - style and rail affairs with a plyeood panel insert.
Last time I tried two coats of exterior primer and three oats of exterior latex flat and the job didn't last two years in places and I had to repair sections of the rails.
SO, I thought to check-in here and see if there were any trucks of the trade one or more of you might share to help me best protect the $130 replacement panels the need replacing now.
