I have to fill some rotted areas in the exterior frame of some
windows. I already have some latex exterior putty which I can
build up in layers. The areas in question are about as wide as a
pencil and maybe twice that deep. I've heard that some people use
Bondo for these situations. Is there a good reason to prefer that
product?

Latex putty will last 5 years, its junk. Bondo the 2 part epoxy will
out last you and maybe the wood.

I disagree....Bondo is a polyester resin NOT an epoxy.

Epoxy is a better material & more expensive than Bondo.

For interior repairs, Bondo is fine, for exterior Bondo is "ok"
except for redwood.

If you want an exterior repait to last use an epxoy ........like
WoodEpox or LiquidWood from www. abatron.com

I have some French doors where a dog scratched pretty deep into the
wood that surrounds the glass panels.

Would your recommendations work for that if I build it up in layers?

You don't need layers with either polyester or epoxy "putties". *Best to
overfill slightly and cut off most of excess with a chisel after it has set
but still not really hard. *Sand smooth when fully cured. *OR - just over
fill and sand flush.

The nice thing about Bondo (polyester putty) is that you can control the set
time to a degree. *Even setting slowly it is *much* faster (minutes) than
epoxies (overnight); additionally, it doesn't blush amines like epoxy nor
does it degrade under UV like epoxy.

Thanks for the good info.

I think I will go with Bondo.

I am going to build a "form" for the repair using some scrap wood.
But it will be a while, the temp right now is 101 degrees.

Take care,
