I was rear ended by a large SUV in my Prius and wanted to fix the bumper damage myself. All I needed was a metal pipe from techshop and about an ounce of car wax and a cloth. With gentle pressure I used the metal pipe from techshop to go in from the back of the bumper and push the dent out. Once the dent was out I rubbed the car wax onto the scuffed areas with the cloth. I let the wax sit for about a minute or two before I wiped the wax off with a clean side of the cloth. After the wax was wiped off it was back to new! I'm really glad I was able to save thousands of dollars by fixing this at techshop! Please look at the picture, I made it at TechShop.
