The hutch was originally stained, so I used a couple coats of Kilz 2 to cover it, then 2 coats of white paint. I hadn't realized before, but the cabinet goes up all the way to the ceiling... even though the trim is about 12" below the ceiling. It was pretty difficult to get up in that space. But I also realized that it would be the perfect spot for some lighting to illuminate the whole hutch. Someday..
I originally wanted to replace the wood paneling in the back of the cabinet with beadboard to match the backsplash, but now that it's painted, you don't notice it as much. It actually looks pretty nice. And luckily for me, the doors and shelves all came out very easily, so it made everything a little bit easier to paint.
We decided to keep the original hardware. It's very unique, and I think it fits better with the house than anything else we'd find. But when I went to put it back on the newly painted cabinet, I realized it needed some help. When a very thorough cleaning didn't make much improvement, I decided to spray paint them. I painted them black and they look brand new!
