NO Bondo is not OK it will absorb moisture if used bellow the waterline. If your putting a barrier coat over it theres a good possibility it may be fine but I would NOT skimp here if your going to the huge expense of this project.
Use either an
epoxy such as West System, System Three or MAS and the appropriate fairing filler (I like the System Three stuff personally) or a Vinylester blister repair filler such as the product that 3M makes called
3M Marine Premium Filler.
I've physically had to remove and repair a number of bad under water patch jobs where Bondo was used and it's NOT fun..
Do it right and use the right products..
