Sup /o/, so i'm not gunna pretend I know anything about cars but I recently found a small dent in my car about where the red circle is and 3 inches in diameter, it's at a spot where I can reach it from underneath but can't push out very well and I definetly can't get a block and hammer up there.

So anyway are there any cheap DIY ways to get a dent like this out, I googled around but a lot of things seem to have pretty mixed reactions.
