I've just done mine with PlastiCoat "Wrinkle Paint" #217 black. It is a very good match in my opinion.
I stripped the whole thing, put a coat of epoxy primer on it, then applied the wrinkle finish according to the instructions. The BEST method I found to get it to "go off" properly (uniformly) was to set it in direct sunlight after the last coat.
I've tried to emulate the original finish a number of times unsuccessfully, I believe the primer coat had a lot to do with the success.
