  Unfortunately for me, I live in a climate that suffers through long winters with salted roads. I only bought my SC last summer, and I didn't drive it during the winter. But the previous owner(s) obviously did. Once I had the skirts removed, this is what I found. I knew there was rust, but I didn't know it was this bad. Pressing on the rocker panel resulted in a "crunch" sound, like squashing a wafer bar.
  Anyways, here's how you remove the skirts if you haven't figured it out for yourself:
  Start by removing the metal screw at the front of the skirt, on the lip of the wheelwell. proceed towards the rear, unscrewing the plactic screws under the car that hold the skirt in place. Once they're all removed, return to the front, and under the car you will see a black push-pin that holds the skirt and the inner fender in place. This must be pulled out, and may actually be the toughest part of the job. Now you should be able to remove the front part of the skirt by lifting it off the metal tab that holds the top. Put the skirt safely aside, so that you don't damage the paint.
  The rear part comes off in the same manner. Put it safely aside too. You may have noticed a long piece of steel resting in the front part of the skirt. This is what was intended to hold the skirt and keep it from sagging. It has obviously fallen off, and if it is still in one piece, we will reuse it. Luckily, mine was reusable.
  There is a similar bracket holding the rear part of the skirt in place, and this had gone AWOL on my car too. I had a spare one on the black SC, so I stole it to use it on my car.
  Before we reinstall the bracket, we have to remove the remnants of the old rivets that held the bracket on. Take your hammer and chisel, and chiseling towards the ground (so as not to risk scratching the paint), chop off all the old rivets along the whole length of the skirt. There should be about ten or twelve of them. Once they're all out, grab a handful of new rivets and the new bracket. Hold the bracket in place at one end and install a rivet with the rivet gun. Do the same for the other end of the bracket, and then do all the ones in between.
  
  In this picture, you can see the rust on the stones as a result of hammering the old rivets out. Now that you have both brackets reinstalled, this is what your rocker panel should look like (minus the cancerous gaping holes). You can proceed to reinstall the rear part of the skirt first. Make sure it is aligned properly, and reinstall the plastic screws.
  Follow up by reinstalling the front part. This is a little tricky, as you have to hook the part in front of the door in, and then make sure that the skirt is hooking into the bracket all along the door. It might take a little fidgeting. Then, assure that the skirt is tucked in between the floorpan and the inner fender at the front, on the underside. pull the skirt as far toward the read as possible, so as to minimize the gap between the two parts. Reinsert the black push-pin, then screw in the plastic screws.
  
  This is what your car should look like now. It looks almost new, and now when you accidentally kick the skirt, you won't hear that annoying metallic rattle! For half an hour a side, I think this is one of the easier things to do to make your SC look good.
