The front and rear cases of the MacBook Air are milled from brushed aluminum, allowing for lighter weight when compared to the previous MacBook cases comprised of plastic. However, the 2.96-pound MacBook's aluminum casing has a propensity for denting under slight impact. Repairing a dent in a MacBook uses the same technique used when removing dents from other aluminum materials but requires a complete teardown of the device to access the damaged areas.

Locate the dent. Power up the heat gun and set it to high. Hold the heat gun 1/2 inch from the dent. Focus the heat on the dent for 45 seconds. Turn off the heat gun.

Step 3

Spray the dent immediately after turning off the heat gun with a container of compressed air. The aluminum will contract and pull the dent out.
