I had someone back into my rear door a few weeks ago & after some dicking around I got his insurance info. I wanted the dent popped out & the OEM paint saved. Chris @ Auto Dent Magicians wasn't sure whether they could save all of the original paint or not. The dent went through the body line at the top & there were 2 shallow creases around the middle of the door where the bumper had made contact. They say that if the dent goes though a body line or if there's a crease in the metal it can't be repaired using paintless dent repair methods. The insurance adjuster said as much & refused to authorize a paintless dent repair until I explained that they also owned a body shop & the plan was to pop out as much as possible & use filler & paint where needed. Well after hours & hours of work you can see the end result below. All of the OEM paint was saved. They had to wet sand & buff the entire car to get the colour & shine to match. The door is now perfect again.
