I don't have any experience with either of these but Popular Science magazine has an ad for a chroming product:

Hot Rod magazine had an article about a company that will re-chrome your dash or other interior parts:

Now I need to find a way to properly repair the wood grain on the dash bezel. Probably involves a thin veneer, patience and a vacuum table.
