Wow, I came to the right place. My apologies for not being more clear with what I want to accomplish. I am not matching color, at least not at this stage but changing it from UU1 to Q5. The drive train and even the entire front suspension, K Frame and all, are out of the car. I need to paint the frame rails, especially where the upper control arms attach, and inside the front valance and nose area. They have surface rust. I was thinking, while everything is out of the car, why not do the engine bay while I'm at it. Trying to get a car with no drive train somewhere for painting, when I'm a year or so away from that, will be a challenge. But, it I could do those areas, and the trunk (no rust) and under the car (no rust) maybe I could get the drive train done next and then have the body painted. Again, thanks for the great advice. I know this is all down the road a ways but I need to make out a plan and budget to finally get this car done.
