So, I have more questions. As I mentioned I have a very old house (ca. 1890.) It's been added onto and on one of the back porches you can still see what the original siding and trim looked like (that's the green picture) awhat it looks like now (blech!) Personally I'd like to tear off all the ugly siding and paint, but that's been vetoed. So my next question is: based on the green picture, would you think they just sided over the existing 1 x 4 trim? There'd be no reason they'd tear it off, would there? If it's there, do I just nail my new 1 x 4s on top of the old?
