I've also started painting over all the red paint. I liked the red paint when I first painted but decided on repainting with the same color I repainted my kitchen with.
Here are the doors before:
The exterior door was never finished after we installed it on the exterior side. The interior door was stained with a walnut color. The interior side of the exterior door was also stain in the walnut color.
I redid the interior door and stained the exterior door with General Finishes Java gel stain.
Just ignore the dirty floor!! The basement hasn't been trimmed out yet. It's on the "one of these days" list!
