My front door needs painting again, I had painted it a couple of yrs ago cause the paint had cracked and burn marks on it. But now where the cracks was before they came back and is flaking off now, so my question is do I sand it down or do I get something like bondo to fill it back in before I paint?

If the paint has lost adhesion to the main surface - sand it down.

Preparation is the most important part of the job.
Follow the directions on the can, prep. time usually takes longer than painting.
