By "wheel well edges", you mean the semi-circular cutout on the outer skin?
Some pictures of your bus and the rust situation would be helpful.

Sure. Bondo has been used pretty widely. I did plenty of forum research. Here is the steps for what it is worth that seems to be working well:
1. Wire wheel floor
2. Rust converter / sealer.
3. Grind bolt hole areas clean for good surface and bondo.
4. Re-apply Corroseal over the floor.
5. Glue down 1/2" runners along the exterior with Locktite PL
6. Add 1/2" iso board and glue with Locktite PL
7. Add 5/8" T&G ply glued to Iso and screwed at the exterior runners.
The Corroseal product has been a good one. Through its hardening process it makes a plastic like film and hardens. Feel like another coat to re-cover everything is a good idea prior to insulation to create a solid near 2 layer vapor barrier.
