Britrover,
Depending on your location (why don't people fill those in?) here is a plater with a lot of experience and is used by many car restorers and customizers in my area. They do chroming as well as plastic, but also do powdercoating, and 24 karat gold plating. I'll be using them for the first time this winter for the 05-06 projects.
