Phil,

I'm a fan of Bondo - where it makes sense and can be painted or otherwise
covered. Clean out the rotted part in the post then bore some smaller holes
about 1/4" by 1/2" deep so the Bondo can be pressed into them and make it's
own anchor points. After clearing out the old putty and drilling the holes,
swab the entire patch area with a wood hardener. I can't recall the name of
the product I've used but it's available at HD and it has the color of
orange shellac but the consistency of water. Apply enough coats so that you
notice a buildup. The initial coats (first two coats) will most likely sink
into the wood. When it no longer sinks in and is dry - you're ready for the
Bondo. This will harden any soft spots in the patch area and prevent further
deterioration of the area. The rest of the post may rot out but the patch
won't fail.

When you mix the Bondo, be sure mix a bit more than what you need. It dries
fast so if you think you need a bit more working time, reduce the hardener
by 25% to 50%. I've found thru trial and error that a 50% reduction of
hardener almost doubles the working time. Temp and humidity play a big part
in determining the working time too. Place enough Bondo in the patch area so
it's slightly proud of the post and let it cure. Then rasp or sand it down
as needed. Prime and paint.

A friend has a wooden post in her front yard with a light attached.
There are 2 spots the size of golf balls that, I guess, rotted out and
were filled with what looks like wood putty. She would like them
repaired. At first I thought of using Bondo, but then I figured the
"plug" would just fall out like the wood putty did. At this point, I'm
thinking that the way to go is to turn the hole into a mortise and fill
it with another piece of wood, dutchman style.

Does anyone have any better ideas?

Thanks,
