Sand before applying Bondo.Follow the directions. It is like sculpting. I suck at sculpting but I am pretty good at body work. You also need one of these. When it dries sand it. Then caress it like a woman. Feel the bondo and know wither you need to add more or sand more. I spray a light coat of primer to get a better idea of how my work will look after paint is applied.
