I had a lot of scratches on my car when I first got it too. I used #80 grit sandpaper then #120 and then finished it off with the "blending pad" I got from a Delorean vendor (they are courser than you generally can find localy). I also did it without the #120 grit going right into the blending pad. It is VERY IMPORTANT that you control the stroke and pressure as you are scratching the surface and if you don't "grain" it straight you have to start all over. On flat surfaces use a short piece of 2x4 to have even pressure. Don't ever push hard on the hood. Finish up with the S/S cleaner (the expensive spray can). After that a little Windex and you can win the next Concours! It is a lot of work to do it by hand, the Delorean shops have power tools that make it easier and faster, but it can be done by hand. If you do a panel you must do the entire panel to make it even and as you do one you will find yourself going around the car a panel at a time. Take your time and the car can look like new! You can start with the #60 and if you don't like it just go over it with #80 or #100. David Teitelbaum vin 10757
