We used slim bars maybe 3 feet long that were curved on the end just for problems like this. Looked similar to these but were substantial maybe 1/2 diameter. Slide between fender and body and push out the dent or rotate to "scrape" outward to remove the dent. These were the only thing close I could find for sale now. Similar but less substantial. The old ones were not that curved on the end more straight and no "Pointed' ends they had a rounded end for less marring.
