Got some rotten bits at bottom of window frames, most standard wood fillers say suitable for interior and exterior use, is this true or can anyone recommend something in particular?
I've previously gone hardener then filler. If you're confident you can cut out all the crap then hardener probably isn't required. Not sure you'll be able to cut that far back though.
