Cost is the biggest factor to re-plating/chroming. It's out of control these days.
I have had good luck with the Scott Drake line which is one of the vendors the mustang outlets buy from.
My original bezels, knobs, and switches are all in a baggie. Everything works just fine and the bezel's look great.
One of these days I'll make me a little plastic-chrome vac machine once I understand all the processes involved.
Yea...Right
Good luck!
