Our door from our garage into our laundry room was in serious need of a coat of paint. It was starting to rust where the former owners dog had scratched it. Since this door is the main point of entry into our house (really who uses the front door), it was always dirty. I spent alot of time using the magic eraser on it in the last few years. Since I'm addicted to Pinterest (yes, very addicted) and DIY blogs, I checked out several people who had painted their front doors black.
So, one weekend when BP was duck hunting, he came home to the door off the hinges in the drive way. I taped off the windows using newspaper and blue painter tape, I also taped alumnimun foil over the very brass/gold handles....which are another project for another day. BP then proceeded to critique my spray painting technique (I think he has a secret love for spray paint), therefore he finished the project. I used a Rustoleum Black Gloss (3.5 cans). It turned out really good (except for the white insides of the windows, but they are not too noticeable). I also painted the brown cabinets the same color as the garage so they don't stick out so much.
It has been a big adjustment not to think the back door is open when peering into the laundry from the kitchen. All in all it was worth the effort.
