2. Gouge out all the rotted wood using a paint scraper, chisel or old screwdriver. Work back to solid wood if possible. Drill a series of 1/4-in. holes spaced about 1 in. apart to allow epoxy consolidant to soak into any water-damaged wood surrounding the repair (see Photo 3). On vertical surfaces, slope the holes slightly downward to form pockets for the consolidant. Don’t drill all the way through the material.

I find that a combination of Shell-Guard RTU to kill the fungis that causes rot, with M-Balm (2 part consolidator epoxy) and E-Wood Putty (2 part filler putty) works wonders for wood repairs. You get to keep thr problem from spreading throughout the wood before you make the reapir. Bondo was just too messy to work with and it wasn't as strong as the E-Wood once cured.

The problem with Bondo is that it is not water proof. If the top coat fails it wll act like a sponge and soak up the moisture.

Here’s a better way. Use Kilz Total One to stabilize the wood remaining after removing the rotten stuff. Then build up the repair with Bondo Auto Body Filler as required. The Bondo mixes easily with its cream hardener allowing cure time to be adjusted anywhere from minutes to hours. Before fully hardened, the filler can easily be shaped with various kinds of rasp tools. When the Bondo is fully hardened, use a file or sandpaper to finish shaping the repair then apply the final paint coat.
