The guest room headboard is done! You can see the before here. The surface was a wood veneer, so I started with a coat of my favourite Zinsser oil-based primer. The paint is leftover from our shutters, garage door and foundation. The colour is a custom Manor Hall tint, but it's a very dark green - almost black.
I finished it with two coats of Rustoleum's Ultra Cover spray paint in clear gloss. I really love the gloss finish - it took the headboard from just OK to something special.
Now we just need to install new baseboard and quarter round, and we can call this room done. So close!
