Removing rust is a complex process, and it's very difficult to get it to stay gone (nearly impossible). The quarter panel happens to be a VERY nasty spot on the Mustang as the rust originated from inside the fender, not outside.

In order to have a shot at getting rid of the (hopefully small) rust spot, you'll need to get in behind the fender and remove all the rusted material. Wire brushes happen to work pretty well at ripping all the loose stuff away so you can see what's going on underneath. You'll also need to take it back a ways into clean metal. Make sure you apply a metal etching primer to the area once you're done with that.

In all honesty, it's very likely that your quarter panel is completely rusted through which will require some sort of fiberglass or bondo work once you remove all the infected metal.

My advice? Pay a pro to do it if you want it done right. It's worth the couple hundred extra it's going to cost you.
