Check the web under spray on chrome or cosmichrome? I had some homemade bike accessories done this way, looked pretty good until I washed the bike with a steam jenny the next year and burnt it off. The guy who did it for me was Darian Demer in Meadow Lake SK. Don't know if he is still doing it or not. Alberta chrome platers in Medicine hat will chrome anything in any color as well, top notch work but you pay for what you get. Hopefully that helps.
You can get chrome in a can, but the most important thing is this!! Paint the entire piece with chrome and clear it in. Allow it to dry for a week at least. Then repaint the colored area and clear it. The chrome paint will almost react with any other paint and if the masked seams touch and it will bubble. I found out the hard way. Good luck!
Both sources I suggested included plastic. If your going to try the chrome in a can method, try the spray bomb method on something expendable before going ahead to make sure the finish is what your looking for and to try out your masking capabilities. Good Luck
The model car guys use a product called Bare Metal Foil to do chrome trim. It's bascially really thin foil with an adhesive backing that comes on a sheet about half the size of a sheet of letter-size paper.
To apply it, you trim it on the sheet using a sharp X-acto knife, peel it off the sheet and apply it to the part. Then smooth it down being careful to avoid wrinkles. You can then trim off the excess using the hobby knife and polish it with a soft cloth. If you make a mistake you can peel it off and start over with a new piece.
It takes some practice to get it right, but it does look convincing on a model car. I've never tried it on a car interior but it might be worth a shot (?).
