Can this be fixed with filler primer?

I bought this fiberglass shell just the other day and it has a decent chunk taken out of the bottom, pictured below.

I bought some filler primer, would it be enough to fill that cracking on the bottom? I also bought bondo just in case it doesn’t work, but I didn’t know if I could fill a gap that big with primer alone. In past experience, TW members have been super knowledgeable, I would appreciate any help! Also don’t worry about the paint blistering I’m fixing that anyways.

 

Fill it, and if its not perfect, use bed liner around the base of the shell to hide the damage from storage and removal.

 

I would use bondo hair, its a fiberglass reinforced filler that will be much stronger. Its usually only used on larger dents or fiberglass damage because of its strength. It takes much more power to sand it down, so use 40 grit on it. Then when its sanded down put regular body filler over it for that smooth look.

 

I'd be more worried about that blistering than the edge- is that just the paint or is that a bad fiberglass job?

 

^^ This is that water droplets or is the paint blistering?

 

I can easily scrape the bubbles off with a fingernail, and the primer underneath is totally smooth. I already got the stuff to fix it all up, and the blistering is actually way worse on the other side. The blistering is just a paint issue.

 

It’s all dry, that’s all blistering.

 

It looks like the chipping is into the fiber so it needs to be filled with a reinforced resin (polyester or epoxy + reinforcing filler). This is a common type of damage seen on sailboats, often from bumping while racing and from coming in to dock a little faster than expected.

If the paint is blistering that badly and it's not a repaint I'd really be tempted to contact the manufacturer and have a discussion with them about it.
