AutoZone does sell dent removers. You can find them in the paint aisle near the touch up paint. They are small, hand held devices that you use to push the dent out from the inside.
There are a few different brands, but they all work pretty much the same. Just put the suction cup on the dent, and then press the handle to push the dent out. Some of them have a light on them so you can see what you’re doing.
They work best on small dents, and they’re not really made for big dents. But if you’re careful, you can use them on bigger dents too. Just be careful not to push too hard or you could damage the paint.
So if you’re looking for a dent remover, AutoZone is a good place to start. Just head to the paint aisle and take a look at all of the different options.
