Stop chrome plated polypropylene from flaking

My question is, what kind of paint/coating/material solvent would aid in protecting a surface that is chrome dipped?

Here is the basic situation:

Parts are chrome plated via a dip process. The top surface(black) is a chrome plate-able material. The material on the underside (natural - Polypro) is a structural material and it does not have chrome plate-able properties, i.e. poor paintabality. The appearance of the underside is not an issue as it is not a show surface. However, over time the plating on the underside will flake off which is not acceptable to the customer.

Please let me know what can be done about this. Thanks.

What you really may want to do, Alex, is rack two parts back to back with only a small gap between them. Then you will get no plating on the back.
