If we are talking metal door, sure you can. It all depends on how deep the dents are. For small dents, get spot putty, for deeper dent, get Bondo. You can get all of these products at an automotive body supply e.i Canadian tire, princess auto or any other automotive paint shop. The first step that you would have to sand down the garage door to the bare metal otherwise this process won’t stick. If you can hammer out deeper dents, then apply filler in layers, then block sand until it feels smooth.
Repairing a small dent in your garage door requires materials you probably already have around the house. There are a couple of methods for fixing dents. Choose one below based on the materials you have at home:
You’ll Need: A wooden block, rubber mallet, putty knife, fine-grit sandpaper, patching material, paint, and primer
The first method
Steps:
- Wash the area with warm water and detergent and allow it to dry fully.
- Place the wood block over the dent and tap it with the mallet to even the dent.
- Sand the area to even it out.
- Use the patching material to cover the dented area and make it even using the putty knife. Let it dry, then sand it down again.

Aluminum or steel garage door
If you have an aluminum or steel garage door, you’ve probably already discovered that although it is fairly maintenance-free, it dents easily. You don’t have to hit it with your car, although that happens often enough. A stray baseball or children using the garage door as a tennis partner or a soccer, hockey net can dent in your garage and lead you to price out a new panel for your garage door. Replacing an entire panel is usually not necessary. Instead, try a dent-removal technique used on automobiles and steel doors to eliminate dents.
The second method
Step 1

Fill a bucket with water and add 1 teaspoon of dish soap. Swirl the water and dish soap with a sponge to mix. Wash the dented area of the garage with the sponge to remove any dirt. Hose it off thoroughly with water, and allow it to dry completely for one hour.
Step 2

Unroll and cut a piece of aluminum foil from the roll that is long enough to completely cover the dent in your garage, making sure you will have enough excess foil to have room to hold the foil against the garage.
Step 3

Stand next to the dent in your garage door. Set the aluminum foil, the lighter and the compressed air canister, with the top removed, at your feet. Pick up the piece of aluminum foil, and lay it flat against your garage door so it completely covers the entire dent. Hold it against your garage door with your hand at the edge of the foil.
Step 4

Light the lighter, and move the flame back and forth across the entire dent for one minute. Remove the aluminum foil. Hold the compressed air canister upside down and spray the dent on your garage with liquid carbon dioxide for 30 seconds.
Step 5

Watch as the dent on your garage disappears. The temperature difference between the liquid carbon dioxide and the heated dent will force the dent to pop out within two minutes. Hose off the dented area of your garage door to remove any leftover carbon dioxide.
