Yup, that's the stuff.
I usually back mine with fiberglass. And use elmer's epoxy putty on the outside. It soaks in a tiny bit, but it doesn't really need to. The epoxy is much stronger than auto fillers, and can be smoothed with a bit of water, which saves a ton of sanding time.
The stuff you're talking about is a thin stuff, right? When I'm thinking of putty, I think of gooby blobby stuff. The picture and later description do make it sound like a resin that would be nice and paintable or spreadable. Just wanted to make sure I'm not missing something. Wouldn't be the first time.... :wacko
