That's how I did it before ( about 2 years ago). The paint slowly came off along the edges anyway. Wind turbulence, washing, etc.. it looked awful.
I know I can kill the anodize with oven cleaner. keeping it off the bright finish edges wont be easy.
EDIT; I have an idea, spray the oven cleaner in a container and brush it on. work it with fine steel wool.
Update to come.
