I bought the "Ding King" product - the one on TV that has a bridge device with puller in the middle. It does work to a limited extent, but you have to recognize the limitations. First, you need to recognize that for $20, you can't expect miracles. Second, its not a precise device. In most cases, the results will be the minimization or shrinking of the depth of most dings and some may ALMOST disappear. But you will never get the car back to exactly where it was before - especially if there is a crease in the ding/dent. I've used the ding king on my old Camaro before selling it and it shrunk some dings in the rear quarter panel. I've also used it on the wife's minivan to minimize a shopping cart dent and some door dings. The dings are still there, but now you have to look for them. It helps that the minivan is a burgundy color that hides them well. On a black Murano, the results wouldn't be as good. So the product is helpful, but its not a cure. For that you need a professional.
