Thinwall tubing, maybe (?), but there's much easier ways already posted are the way to go.
I have aluminum frame blocks to use for this. A hardwood block cut through with a Forstner bit then cut in half would do the trick as well. It won't completly remove the dent, but will minimize it, make the tubing round first, then fill what rolling the dent won't.
