Dont gamble. Sand or grind it all out and redo it yourself. This way there are no doubts

Let me go one step[ further. This is just my humble opinion, but use a good quality filler. Bondo is OK, but it does not sand nearly as well as, for example, Evercoat Rage Gold. I always use Rage Gold, and it is much easier to use, shape and sand.
