Thanks, but it looks great as long as your about ten feet away. Given that they're up on a soffet they do look fine. I'll admit to not taking the time to make them perfect circles though, just enough to get all the edges smooth. If I do one for an electrical box, I'll probably add another piece of flashing to the front for more rigidity. The holes for the rivets are "eyeballed" on the drill press so they may not be totally symmetrical.
I do want to stress painting them, raw aluminum, is different than painting steel, etching primers won't work, or plastics, bonding agents don't work. The aluminum oxide needs to be removed prior to painting, and there is oxide on it whether it looks like there is or not. I wash them with dish detergent and an abrasive 3M pad, grey or red will do fine. After drying them, apply a light coat of primer specifically made for aluminum. After a ten minute "flash off", apply another light coat to fully cover. Let that dry for 36 to 48 hours depending on the temperature, the warmer it is the less time needed but I'd let it cure for at least 36 hours to be safe and get a good bond. After that a couple of light finish coats and you're good to go. Home Despot carries Rustoleum Aluminum Primer so it's easy to find.
