yuck yuck yuck...
neither of these are good. fiberglass filler is for people who are gonna get rid of the vehicle soon, and are dishonest. bondo is for the DIY'er in the suburbs, who doesn't want to spend money, it shouldn't even be sold on teh shelves at stores.
if you are gonna just put mud in the hole, then do it this way... first, cut the rusty edges off until you have pure clean steel, then use 40 grit flexible grinding disk to strip down the clean metal 2 inches around the repair area, then go to a good paint store, and buy some "all metal" or evercoat "metal-2-metal" and fill in the hole wiht that stuff. it is comprised mostly of aluminum, and will hold up in thick patches. there are 3 colors of hardener...
white is waterproof. you can harden any good filler with any of the three colors.
oh, and top of the all metal or metal2metal with evercoat z-grip or somethign similar. don't go with anything you can buy at walmart, it isn't worth the headache.
oh, and top the z-grip off with polyester skim coat, like usc icing, or evercoat thin ice.
