I started to work on the rear quarter panel. It was heavy with body filler. It was over 1 inch thick in some places. Once I got all the body filler off it was obvious that there was a major dent in the quarter panel. My work colleague let me borrow a H & S 5500 UNI-SPOTTER STINGER STUD WELDER-Dent Puller which my son helped me utilized to pull the panel back out. Really happy with the results.
