Phil Ledgerwood offered chromed posts a few years ago, but said that the quality wasn't good enough so he stopped doing them.
The current coating on new Morgan seems resiliant, but don't use any sort of polish or it will shine the surface and become patchy.
My 2005 has a coating which is best described as thinned grey hammerite. I doubt it was a diy job in the first three years, so is probably factory.
I gather from enquiries that chrome plating aluminium isn't easy and a base application of copper first is essential.
I suspect your 2005 is the same as mine although I was convinced it was powder coat of some form. Having stripped it I think it's paint. How well it lasts is a matter of pot luck. I don't remember when I first noticed an issue but it was a long time ago. It wasn't addressed as I was using the car to get to work and I thought the comercial solutions too expensive.
