Much better

Now if you had only one good fender and one mangled one, you can make an FSP based on the good one, then flip that FSP inside out as a pattern for the bad side.

FYI, they aren't as "delicate" as you may think. Some of the metalmeet guys made some FSP's from a F/G car as a group build on a home-built aluminum car, mailed the FSP's around the world to participants that were coming to their yearly event, where they took the FSP out of a flat envelope, and made "their" part. They all got together at the event and put the puzzle pieces together.
