I found a 1989 Girls Giant Iguana 18 speed bike that someone left for dead, and decided to revive it. I converted it to a 27 speed with Shimano trigger shifters, but wasn't happy with the yellowing, chipped white frame.
So....I added a bar on top so it didn't look like a girls bike anymore 3 coats of Rustoleum Auto primer and 6 coats of Rustoleum Professional High Performance Enamel (Aluminum). I finished it off with 5 coats of clear enamel. I know it's not the greatest thing in the world, but I'm proud of it.
Here are a couple of pics.
