Often before chrome is applied to parts, a clear gloss agent is sprayed on to increase the adhesion and finish of the chrome. The content and quality of this agent varies greatly. Sometimes it is perfectly fine to paint over (Tamiya chrome is often like this)- it can be a good painting surface. But sometimes the gloss needs to be removed (Simple Green, alcohol, or household bleach will usually do it). Occasionally the clear becomes a gummy mess as it's stripped- a good scrubbing with an old toothbrush and some dishsoap usually fixes this nicely.
