BONDO! 

LOL!  I love saying that.  It is an implied joke, implies that it is crap.

The thing is, I have learned to respect the material and use it where it is appropriate and not use it where it is not a good choice. 

Another thing is, they make products for a lot of different applications. 

I was painting the windows and trim on the exterior of my house and found a section of door sill where the paint had failed and the oak had rotted. 

I cut out all of the soft wood and rebuilt the sill using BONDO!  I made a perfunctory mold to establish the boundaries and contain the material while it cured.  I removed the mold and did some rough trimming of the exterior profile with a blade while the BONDO was still soft.  I will sand to the final profile when it is fully hardened.

If this does not hold up, I will completely remove and replace the sill.



FYI - the rot is on the left edge, where the door hinges are, so there should be no foot traffic on top of the repaired areas.  We will see.

Sounds like a good plan of action to me.

water putty is a good thing too Attached File

I'll have to try some on my next job.  As you know, there is always a next job for a homeowner.

Bondo is great for drywall repairs

Yep bondo for repairing wood/pvc trim and covering screw holes is the way to go.
