Learn how to remove interior trim panels
The standard paintless dent repair method requires gaining access to the interior side of a dented car panel then slowly and methodically pushing the dent with metal hand tools until it returns to its original shape. Sometimes we can get to the backside of a dent on a door by using wedges and a protector board to create a small gap between the door panel and a downed window. Other times we have to take apart the car and remove items such as interior trim panels, tail lights, head lights, headliners, window glass, and fender liners.
Removal and reinstallation of trim panels and other items is a skill that is learned over time. Auto manufacturers will follow similar methods and trends. However, the way cars are built is constantly changing and varies greatly from model to model. For example, removing an interior door panel on one car might require only a few easy steps, such as unscrewing one bolt and lifting up on the trim panel. Other models may require multiple complex steps, involving fragile appliqué, hidden bolts, sensors, and electronics. When I first started taking apart cars, it was a lot of guess work along with trial and error. Breaking stuff happens. The goal is to limit mistakes and get more efficient at disassembly.
I recently discovered a new resource for interior panel removal, that is very helpful when I come across a vehicle I have not yet disassembled. DFC Garage on YouTube has hundreds of videos that show you how to take apart all kinds of cars. The creator of the channel is a German window tinter and vinyl wrapper, who has graciously shared his knowledge of car disassembly for free.
