Bare steel bodies are cool to look at, but it's time to start the bodywork phase on the S71 Olds. This time, we sprayed the underside of the car with PPG DCX 1791 etch primer and then DP90 epoxy primer. Our painter Randy uses SATA spray guns and 3M safety masks and gloves with this stuff. DP90 is black and tough, so it will form the base on the bottom of the car body. The next step is to brew up some DP60 - a blue version of the same stuff - to shoot the inside and outside of the body. Then the filler work begins!
