i'm going to school to become an autobody tech.. and they are teaching us how to "work" metal.. i've gotten big ass dents outta fenders with very little body filler by working the metal.. you can return the metal back to its "orgional contour" with the proper technique and heat just my .02
if you get fed up with it before SZ or next fall some time.. you can drive it over to me and i can do it for cost of materials
