Hi there, I'm in the process of taking my boot lid back to bear metal but after I'm going to give it a layer of body filler and then primer it. Any recommendations on which brand of body filler and where to get it from. As this is my first time doing it I'm totally new to the whole experience. Oh and i'm located in Adelaide.

Also and any help on "how to apply it" would be much appreciated since i've never done it before
