I've had pretty decent luck knocking fenderwell dents out by removing the tire and using a rubber mallet or deadblow hammer. For the smaller ones I use a piece of flat stock or hardwood dowel. Rinse the wheelwell thoroughly and let dry before this job, but still use goggles and a hat. Road dirt still manages to fall out. That being said, my sons truck when he returned from Seattle was squeaky clean underneath. All that rain sure keeps the undercarriage clean!
