Now comes a crucial step. Grab your Parma detailing pen, uncap the large side, and go to work on all those body lines. There are door panels, window trim, hood lines, trunk lines, intake scoops, door handles, and the list keeps on going. In this picture, you can especially see the lines traced across the roof. Using the fat edge is much more forgiving than using the thin one. You are less likely to notice areas where your hand was less than dead steady. I highly recommend one of these detailing pens for your car, the effects are outstanding!
Once you have completed detailing the car, give it some time to dry, and then grab a pair of straight scissors, a pair of lexan scissors (or, as in this picture, get a pair of cuticle scissors, only $4 at your local store.) and a good xacto knife. Use the straight scissors to cut off excess polycarbonate below the body lines. I also use the straight scissors to cut pie slice shapes into the wheel well openings. Use the lexan scissors for any area requiring a curved cut. Follow the body lines closely, but never go over the line! You can't add material back to the car.
Finally, we used the xacto knife to cut out straight lines. Do this by firmly dragging the xacto knife down a straight line, but don't pierce the body. Next, grab the area you wish to remove, and fold it at the area you just scored. By the time you have wiggled this piece back and forth a couple of times, it should come right off in your hand. Pretty nifty, huh?
Once the body is fully trimmed, use some sandpaper (we used a 35,000 rpm dremel tool with a sanding drum) and sand down all the edges you have just cut. This will get rid of any sharp spots or flashing.
