Exterior door Jamb and Bottom Plate Rot Repair

My 14 yr old house has two doors with some rot issues. One is a 32" single opening side garage door with some jamb rot and the other is a double opening french with 36" doors with jamb rot and bottom rail rot on one of the doors. They're both exterior rated fiberglass with wood jamb/casing manufactured by Thermatru. The french door is on a patio and under roof, the other single is a side entry as shown in the photos. Thermatru warranted the lost argon seal in the windows but said the rot was not part of their warranty (disappointing to say the least).
Two questions:
1) Has anyone tried to cut out jamb rot (like as shown on both doors) and added a filler piece and sanded painted etc.? The wood seems to be solid above the rot in the jamb.
2) Relative to the french door bottom rail rot; Can i clamp that up and fill it with some gelcoat or bondo or something and sand smooth paint?
I'd like to try something short of ripping these two doors out. They are the only two that have rot out of 10 doors with this issue (4 of the other french doors windows lost seal but they warranted that).

Looking for suggested methods and materias to use/patch/glue


l and any other recommendations.

Thanks! FF

I've tried it all... there's a 2 part wood repair 'bondo' product that you can use with a putty knife to fill it in and sand. Not the best option. I've also cut the wood out abt a foot up and replaced it with new wood. Not the best option. I lastly stopped being cheap and spent some money and pulled those trim boards out and replaced it with pt wood and vinyl trim. Now it looks good and will last longer than the rest of the house trim. Removing those boards aren't that difficult of a job after you do it, but it will take a few hours.
