Rebuilding top part of the door
We did this pepair. Can't remember all the details. Hubby took the door apart and we just looked how it was . I remember he used exterior plywood and the repair took several days. A step by step process and then clamping. I used contact paper to complete the repair. We ended up with a better door than from the factory. Hubby is sleeping. I'll will ask him if he can remember any specifics.
