Wood filler on exterior trim?

Body filler works great in that application but it's best to use a brand other than Bondo as the bondo brand is known to absorb water. I use evercoat products as they don't absorb water and they are easier to sand.

I use bondo on all sorts of applications that I am going to paint.  As far as I know I have never had a failure.  I watched painters where i worked and they used spot putty also - dries real fast - just don't apply too thick.

Bondo works well. I had a window in my old house where the water just pooled on the exterior sill. Prior to finally having it replaced and the trim wrapped with aluminum, I affectionately called it my "Bondosill." The caution with any filler is that you need to get ALL of the rot out and then use wood hardener to prep the remaining surface. Wood hardener works like a charm when used properly, and it's necessary to prevent further rot.

Any two-part epoxy as far as I know should be good for resisting the elements, especially when painted. Shaping is easily done with a rasp or sander. I wouldn't recommend a chisel as there is no grain to an epoxy filler and as such it isn't very easy to accurately remove material. It's a lot like chipping concrete with a cold chisel, which if you've ever done it is most definitely not a precision task.
