Not sure man, I bought it with it already sprayed....the paint led me to believe the engine had been pulled or opened up and therefore possibly wrecked but I dont believe the engine has been apart at all (nuts/bolts and screws are clean...no scratches) My guess is its some high temp matte black paint.
I also believe the car was once creame colored because the door jams and t-tops are creame so maybe the previous owned painted it then
