|Bondo for repairing wood?||mr_spin|

|My kitchen window on the south side of the house is basically hollow in some places. A hole developed at some point which was badly patched, some pests got in, and a lot of the wood on the bottom edge of the lower sash is basically shredded inside like cotton.
I don't want to replace the window. It's double hung and the top sash is fine. I could have another sash custom made for lower window, but I heard I could use Bondo to fill the cavity and make it like new again.
Anyone ever done this? I was down at the auto store and there seem to be all kinds of Bondo. What kind should I use?

|There are also some wood specific replacement puttys out there. My concern with bondo is that I'm not sure how well it would stick to the original wood. If I were going to try it, I think I'd go with wood-specific fake stuff.|

|One of the jobs I've done as a newspaper guy is several years as home improvement editor and writer. A couple of years ago I had the same problem with some sills on an old shed, so I did a story on ways to fix it (nobody goes into journalism for the money; it's the ability to do your own research on company time).
There are several products made to repair those things. Ordinary wood dough sort of works, but it's not ideal and doesn't seem to last well.
I haven't used Bondo on anything since fenders in high school and don't remember its properties, but I'd be surprised if there isn't something better now. I threw myself on the mercy of Home Depot and the guy recommended an epoxy-based, two-part compound that's specifically made to fill the voids in rotting wood (sorry, can't remember the name). I troweled on about $20 worth of it, let it set, sanded and painted and it still looks good a couple of winters later. Thinking back, though, it would have been cheaper and probably no slower to replace the wood, maybe filling the joint with epoxy.
On the other hand, Bondo in quantity is pretty cheap, it's easy to work and you're going to be priming and painting over it anyway. Worth a try.

|Check out www.rotdoctor.com. They have a clear penetrating epoxy that soaks into the rotted wood and basically turns it into solid plastic. You then fill in the holes with a thickened epoxy putty. Completely sandable and paintable. I have used their products in the past for restoring boats and can tell you that they work.|

|You will find it pre-mixed in the paint section of Home Depot.Get a couple plastic disposable sheet rock tools to spread it.If you have a big void don't try to fill it all at once. It might take several applications.Try to keep it as smooth as possible. This will make sanding easier.|| |
