I have an overhead garage door that is apparently made of a composite skin over composite bracing. Although painted, it appears to soak up rainwater and rot. I tried patching it with bondo, but that didn't work. So now I'm looking for a replacement that is impervious to water.
The dealers around here have wood doors, and steel doors. They claim the finish will protect them, but I'm not confident since wood rots and steel corrodes.
Are there better options. I would think fiberglass or aluminum would be better.
