Yeah I was looking for them too, wound up painting them. I used a HVLP sprayer with a super flat black paint. A spray can would work but in my case I tried a sample and it took almost the whole can for 2 coats. Worked like a charm. Left the rails white (since they were already up) and it actually turned out very cool. All black would have been to dull IMHO. I also have the projector wall black as well. You can check out photos of mine at my website under the "hobbies" link.
