Replacing a damaged door skin: It can sound so daunting at first, like some epic struggle rife with jagged metal and flying sparks. But this job is considered simple in the world of bodywork.

Why not just replace the entire door? Sometimes beneath that rusty, damaged or poorly repaired outer skin is a perfectly good inner door frame. That was the case with our Mini Cooper S. Now consider the fact that new and used doors for our car trade in the $1000 range, while properly fitting skins sell for around $100 from places like Mini Mania. The choice seems pretty obvious, doesn’t it?

Our expert body man, Tom Prescott of The Body Werks in Holly Hill, Florida, showed us how to properly replace a door skin using modern adhesive. We chose adhesive instead of old-fashioned welding because it’s quicker, doesn’t distort the metal, and has less of a tendency to rust later on.

Step 1.

Our bodywork guru, Tom Prescott, came up to our shop one evening to show us how to properly change a door skin on our Mini Cooper S. Notice that we used a clean, open work area for this job and rested the door on a good, level stand.

Step 2.

The next step was to grind the crease off of the old door skin. We used a 40-to-50-grit grinding wheel and were very careful not to eat into the door frame. Spot welds can also be drilled or ground out on the door’s backside. Hammering with a chisel, however, will likely damage the delicate frame.

Step 3.

Once the crease was ground off and welds were removed, we gently started prying off the door skin with a chisel and grinding away the last little bits.
