let me start by saying I am in the group that feels the little dents here and there add some character to a defender. That being said, will bondo work on the aluminum? Can you bang the dent out most of the way and use a little bondo to smooth it out or is a waste of time. I talked to a body guy about it and he said he didnt like doing it on the aluminum. Is he just a perfectionist or can it just not be done?
