It doesn't appear to be painted Kim and every reman I've seen has been painted. I used to buy any warranty converter cores I could from dealers for the converter shop. I was asked to do this as I knew that not all warranty converters were being sent back to the factory. I had contacts with people I knew at dealerships and the boss knew this. Also, prior to getting into the automotive aftermarket, I worked on the back counter with the mechanics at a GM dealer. I can honestly say, that I never saw an OEM converter painted while there. The same held true for the Chrysler, Ford and Import warranty units I could buy.
