the fiberglass wont work, it contracts at a differnt rate than steel, so it will crack over time, because it doesnt have the same properties as steel when it comes to flexing.
If your trying to stay away from welding, then glue a patch like juicedmini said. The Fusor metal bond works well. However Ive had it shrink in the past when gluing holes for a spoiler.
The best way is still to weld it.
