Dear Jimmy,

From our experience, plastic reflectors are better off to be Aluminum coated using Vacuum metallizing method.

Not only more expensive, the chrome electroplating will make the reflector color bluish and dark.

Depending the type of plastic substrate and the bonding strength required, there are several kinds of base coat to use.
