Door Shells vs. Door Skins
Do I need a door skin or do I need a door shell? That’s one of the most common questions asked when it comes to repairing dented or rusted doors. In this article, we’ll clarify exactly what door skins and door shells are, and we’ll give you a general idea of what bodywork is required with each in order to help you make a more informed purchase.

All car doors consist of a frame to which trim and window components are mounted, and an outer metal layer that’s attached to the outside of the frame. A “door skin” is the outer metal layer only. A “door shell” includes both the outer skin and the door frame, and is shipped preassembled with the skin already welded and bonded to the door frame. Door frames will also include the metal window surround, unless the vehicle uses “frameless windows”.

The big decision whether to purchase the less expensive door skin or the more complete door shell rests on the answers to two questions: one, what is the extent of damage on my vehicle? And two, what is the availability for my particular year, make, and model ride? Let’s take each of these in turn.

Door Skins

A door skin must be lightly hammered onto the door shell, crimped around the edges of the frame until the metal is flat, then secured in place permanently using either adhesives, welding, or brazing. “Brazing” is a metal-joining process where a filler metal is heated to its melting point, then distributed between two or more close-fitting parts to create a seal.

When a door shell is manufactured on an automaker’s assembly line or an aftermarket supplier’s factory, the joining process is typically performed by robots that spot weld with pinpoint accuracy, and it’s difficult to match those levels of perfection by hand.
