What happens here

Once the Bondo is completely dry, proceed with sanding. Use a 3x4 orbital sander equipped with a dust extraction system to sand the flat surfaces of the door. The presenter uses Filmtec 320 grit sandpaper for this task. For contoured edges and panel details, switch to a fine-grit sanding sponge, such as an Eka Silk sponge, to achieve a smooth finish without damaging the door's profile. Continuously check the surface for smoothness and ensure all Bondo is flush with the surrounding door surface.

Goal: Achieve a perfectly smooth surface by sanding the Bondo flush with the door.

we'll come back and sand it. You'll be able to tell if you need to do a second coat of Bondo. Wherever there's dark spots, you can see where it sands it. You can see where it's it's lightened it up and there's spots that just shrank a little bit too much cuz the divots were pretty big. So, we're going to have to just skim one more coat of Bondo over here. We'll sand it one more time. When you got big divots, Bondo does shrink, you know, quite a bit. That's one of the drawbacks to it, but it's the only way to completely eliminate a divot.
