Has anyone had experience with welding sheet metal on the body? My RC has some damage under the driver's side tail light which is too bent to pull out. The body shop I went to said that they if they welded a replacement piece in, it would require that the whole side of the rear quarter panel be smoothed since welding on the flat sheet metal will cause waves in the metal. Has anyone had any experience with this? Am I getting the straight story? What type of welding is best to do this type of repair? Needless to say, I am trying to do this at a reasonable cost. Thanks.
