Is it necessary to remove the door panel when having the dent repair ?  The dent repair in wales will not remove your door panel.  They have special metal tools which are designed to slide behind the collision bracing. Actually, there are a lot of areas that can be accessed by the technician.  Some people are having this perception that dents will completely disappear when the dry ice is placed on the surface of a heated dent. Due to the differences in size, shape, depth, and location of the dents, sorry to say but dents cannot be removed this way.
