Sandblast it and primer it. Depending on the blast profile, you may be able to epoxy prime followed by color. FYI, you cannot go from etch directly to color.
Usually you need an aggressive blast to roughen up the chrome, don't need to remove it. The aggressive blast usually means you will have to use a surfacer primer to fill and then sand before paint.

I have done this many times over the last 25 or so years.
