The drip rail mouldings are stainless. Be careful if you are going to polish them however. The polishing process on drip rail mouldings (coupe and fastback) seems to shrink them a bit making them a lot harder to install. I have my polisher knock out any dents and prep for final polishing, install them on the car, and do the final polish on the car. It work very well. As a side note, I have not had any issues installing the Dynacorn reproduction drip rail mouldings (fastbacks only, coupes.....another story). They seem to fit well.
