It don't sound like your worried about how the repair looks, not repainting etc etc/???

If yes, don't use body filler, it absorbs water, will swell and degrade. It will absorb humdidity needs to be completly sealed.

I think you would be much better off with silicone. Just buy at the local home store.

a fiberglass reinforced filler like tiger hair will be a better choice than bodyfiller, like lloyd said, the bondo is not waterproof
 
How'bout just straight up fiberglass patching? That fiberglass cloth stuff that you apply with the 2 part liquid. I've got it on the clean out doors of my combine and the cab corners of my pickup. As long as the metal is good and clean when you apply it,it holds like iron.
 
I would wire brush it to bare iron, cut strips of aluminum (20 gauge to 16 gauge in thickness to cover the holes plus 3/4 inch lap onto good. Then I would use windshield cement (urethane) or door and window sealer (urethane) in a caulking frame, to lay down beads under it. Then sheet metal screw every 3 to 4 " to smash the sealer (put a disposable plastic sheet inside to avoid irritation that you didn't)
After screwing it down evenly (more is better)
Cover the outside with the same sealer spreading it with a putty knife like decorating a cake.
Do not use silicon sealer, or painters caulk, or roofing cement, they are no answer. (urethane it is) It will take several days to cure completely but it will last. Jim
