Wood Garage Door - Rot Repair

I have a garage door that seems to be rotting in one spot. The rest of the door is in good condition so rather than replacing the whole door, I'm wondering if there is a way to repair it. Please see the attached images. Any input would be great.

Thank you!

 

How are you set for woodworking tools? Saying what to do... "replace the rotted out sections" is much easier said than done.

 

I'm not handy with woodworking nor do I have the tools. Speaking to a co-worker today, he suggested liquid wood epoxy. Is that an option? He did not see these pictures. When you say replace the rotted panels, I assume the entire panel going across would have to be replaced? Can these panels be bought or do they have to be built?

 

Yeah if you can get that liquid epoxy to defy gravity that would be a real trick.

With the skills you have you might as well just Bondo it. Remove as much rotten wood from the hole as you can, then use a wood hardener. Once it's dry, fill it with bondo. Once thats dry, grind it down flat and reapply as needed. Grind/sand it flat. Caulk the gap where your panels meet the bottom rail with something like Loctite Door and Window Polyurethane to hold it together. Then prime and paint the bondo. Expect to replace the bondo every year or two.

 

A correct fix is to replace the rotten sections of wood. After all, the wood is the structure of the door. Since you don't have tools or woodworking skills I would screw a plywood brace to the inside of the door. The brace should extend about a foot beyond the rotten area. Screw through the plywood and into good wood on the door frame. that should help hold the door together.

You also should remove the old rot and caulk. Use auto body filler (Bondo) to fill in the rotted area. Then caulk the seams and paint. Even though all this is cosmetic it's important to keep the water out and slow the spread of rot.
