Go to an office supply store like office depot or office max or wal-mart and look for dust-off or something else of the kind and just turn it upside down and spray on the area. I actually tried this method on a few of my dents and it worked on a few.. but when my friend brought her car back from a fresh fender bumper it wouldn't work, btw her car was a 2009 nissan altima.mind i ask, where u get compress air from?
