I do paint some and have rebuilt 4 totaled cruzes. I'd think it would be paintable. The hard plastic could be cleaned, scuffed, cleaned, masked, adheason promoted, and painted. There are a lot of edges where failure could start. It won't have oe durability, but it can last and look good for a long time. The paint won't stick as well to the softer flat plastic behind the hard grill surround. Cleanliness is key with plastic. Sometimes the mould release agents work against paint adheasion. It won't be cheap as the time and materials are expensive.
