I have a dent on my hood about 4 inches long. It isn't a circular dent, it's more of a line or crease. I bought a heavy duty suction cup it try and pop it out, but no luck. Does anyone have advice on how to remove dents? I was gonna try and push it out, but under the hood there is a black cover. Is there a way to remove the black underside of the hood to do so? Thanks!
