As the designs slowly move towards actual physical items, it occurred to me that some of the JBL drivers I have, eg 2123, have exposed aluminium on the frames when mounted. This will look odd with the other drivers I have, so I would like to paint them.

My plan was to mask the cones/surrounds well, give them a light sand and hit them with some black semi gloss from a rattle can. Are there any issues with doing it, ie the finish JBL uses and compatibility with some sorts of paint?
