Painting a chrome timing cover

I don't know if this will be a good idea or not, but I have had poor experience with chrome, it usually pits and rusts a lot quicker than good paint.

So I have seen the chrome timing covers for around $32 on eBay, from Trans-Dapt Performance Products. I'm considering buying one and painting it. Anybody have any thoughts on this idea? I know the chrome would need to be etched somehow for paint to stick...
