That’s some door ding!
Because the dent is too deep to fill with body filler alone, the first step is to pull the dent out. Using various tools around the shop, such as a slide and body hammers, the metal is teased out until is close to it’s original shape.
The next step, as seen in the third photo, is to smear a thin layer of body filler over the damaged area. The body filler, after it hardens, is sanded until the damaged area is totally smoothed over and the panel has the same smooth lines as it did before it was damaged.
After a bit of priming and painting the repair will be complete and the car will be as good as new.
