Body Repair

Dose any one know if a 3 by 6" inch hole can be fixed with Bondo and Bondo metal mesh? I'm not sure if it will hold.

Won't work.
Why do you say it wont work

Too large an area without some backing the repair will not be stable, you would need to weld in a patch or back up the work in some way.

Is the bondo filler water proof or do I need to use fiberglass first to repair a hole and then the body filler

Fiberglas first.
