I plan to do a lot of research before trying my hand at color sanding the paint. My plan is to start on the trunk lid with around 1000 grit (maybe finer). It will take more work but less chance of blowing through the clear on my first try. Worst case scenario is if I don't like the results after buffing, I can just cover the rest of the car, give it a light sanding and hit it with another coat of clear. The trunk can be isolated from the rest of the car so I am thinking that may be my best bet.
