Good deal, George! Be sure to have a sharp #11 blade. I will often have one blade for trimming from the sheet, and another for trimming the foil once on the car. Some people don't even put the blade in a handle, just hold it between the thumb and index finger. Use just enough pressure to make it stay put, then after it's all trimmed, go back and burnish it down. A little bit of luck, skill, and practice will be your friend!
