I worked on a 1987 Silverado last summer that had a painted, plastic dash cover on it that was about a year old. It looked so good, that I had to put my hand on it to know it wasn't the original dash. It does feel like painted plastic, as oposed to the padded feel of a real dash, but it looked very factory. He did have it painted by a professional.
