I need some very detailed help as I have absolutely no idea what I’m doing. I have started what I thought would be a simple job of replacing the carpet. I pulled up the old stuff and found that the back of one of the front seat boxes was rotted. I have marine plywood, I also purchased some bondo fiberglass resin and cloth. Will this be sufficient to fix the issue? If so, how exactly do I go about fixing it? If not, what else specifically do I need? Please keep in mind that this is my first boat and I have no fiberglass experience and no real repair experience either. I will try to post pics later. Thanks for any help!
