"I never expected to see them pain stainless steel though. Those cars look sharp!"
I don't think they were painted. Take a look at buses and subway cars with vinyl wraps on the entire side of the body depicting ads.
I'm sure those ex-NJT Comet 1's got the same treatment. painting is expensive and there's the issue of paint adhering to stainless steel.
I think they were wrapped. It's probably cheaper.
