"Wonder putty" for window repair: epoxy?


Don't mind that name--that's just what I'm calling the stuff. The stuff being what a guy would want to use to fix a rotted window frame.
I've seen this stuff, both on the tube and in the flesh: a putty that dries hard and white, and is perfect for the repair I need to do. I have a window sash with a rotted-out corner, maybe 3-4" of wood gone completely. My plan is to clean out all the rot, embed some metal in the corner and use this stuff to rebuild the frame. Even thinking of making a small silicone mold for the window-stop profile to replicate it.
Anyone know what this stuff is, and where to get it? I'm pretty sure it's some kind of epoxy with fillers added. Probably not cheap, either.

Not the stuff I was thinking of.
I've used PC-Woody; in fact, I have a couple of cans of it now. It seems pretty strong, but this other stuff I've seen seems even better.
Have you (or anyone else here) used PC-Woody to repair large missing pieces in wood?

PC-Woody is as strong/stronger than wood and you can work it just like wood. How would something else be "better"?

Dunno. Just checked that batch of PC-Woody I mixed last night. It seems plenty hard and stable enough. I think I'm going to pick up a couple cans of it and go for it. It's a lot cheaper than that other "system" suggested here.

I think you might have been overthinking it. The final result is just like wood except no grain. Be aware there is still prep that may include other products just like any other systems.
That company is a very innovative small company which makes quality stuff. A buddy is a chemist and he used to work for them. They don't spend a lot of money on marketing (probably don't have it). Their trademark marketing is the soda bottle with various objects glued to it ( http://www.pcepoxy.com/ for current version )with their flagship PC-7 epoxy that was on the counter of every hardware store in my region.

I've used it since the late 80's to do rotted / deteriorated sill & sash repairs I recently (Fall 2006) rebuilt a rotted sash corner about the same as yours....I drilled & embedded some 10-24 SS threaded rod.
very good stuff, not cheap but well worth it. Can be dyed, painted, drilled, etc
forget the silicone mold, just putty knife the stuff close & sand, plane, saw, scrape or chisel it to shape.
email me privately if you want photos of my repairs or any other info
cheers Bob

Thanks. Looks like good stuff, but yes, expen$ive: more than $60 for a quart, which I'll probably need. Of course, the client'll be paying for it, so maybe it's OK. (On the other hand, I'm going to call tomorrow to get a price on a new sash. I got a price last week from a local place for a larger window, about 30x36, and they quoted me a surprisingly reasonable price: less than $150, including the "horns". Since this is a lower sash and smaller, presumably it'd be cheaper. And by the time you figure in all my time, it might just be better to get a new sash made.)
I just mixed up a batch of PC-Woody; tomorrow I'll see how nicely it sets. Have you ever used that stuff?

I fixed my kitchen window and a few others several years ago using Bondo automotive body filler. I understand they make a product for wood now. I took out all the roted wood and treated what was left with wood preservative and wood hardener. No problems since then, I think this was about 10 years ago.
