Yea, I agree. Way to deep for bondo, but wouldn't be too hard to clean up with some fiberglass. Just use something to cover the body a little bit behind the dent so you can get the basic shape of the car (you can get professional mold wax, or use some vasoline or tape a sheet of plastic to it). Then use a piece of fiberglass cloth or mat a little bit bigger than the dent and use the part of the car that you covered as a mold and make a small fiberglass panel. Then once it's hardened trim it so that it fits into the dent (I recommend trimming it a little smaller so that it goes into the dent about 1/8" so that you will have some strength and leaves you room for sanding). Then sand down to the bare metal anywhere the fiberglass will be and about a 1/2" past the dent. Use some of the resin to secure the panel in place, then layer it up with fiberglass mat or cloth till you have it just past the surface of the car and then sand smooth. Once that's done you're to the point where I think is the only time to use bondo, and that is to fill in tiny air bubbles that you may have in the fiberglass.

Keep in mind that when fiberglass resin is setting up it creates heat and may melt plastic if it's thin enough. I've used saran wrap before to cast a mold of a plastic vent from a Mazda pickup and it's a good thing I wasn't going to be using the vent since it almost fused the saran wrap to the vent. If you use a sheet of plastic I recommend testing it with a little bit of resin first to see how it will react to the curing process. Also, be sure to cover below the part you are using as a mold since the resin will run on the side of a car, and be sure to place something on the ground under the car there as well to catch any resin that drips off.
