October 2019 I hit a concrete bridge abutment. Paid $3500 to have the boat repaired.
August 2021 the $3500 repair job was failing - Soft spot developed. They said sorry but no warranty.
August 2021 - I tried to repair it myself. Basically ground back the soft spot and appiled a bunch of layers of resin and fiberglass. It lasted almost a year.
July 2022, I hit a stump with a piece of rebar sticking out and damaged the area again. Unbeknowndst to me, my 2021 repair was also failing and I have put a hole in the exactly same spot. Ohio River is tough on boats.
Late July 2022, I repair it again. This time, I ground back a lot further. I dug out as much of the wet foam as possible. Put a fan on it for 24 hours in 100 degrees direct sun out so it dried decent. The rest of the foam is still wet..... once I felt the area was pretty dry, I stuff the cavity with bondo. A lot of bondo at that. It harden nice, I sanded it down, feathered it our as best as possible. The bondo was basically a "strucutral layer" between the fpam and the outter layer. I then applied a bunch of layers of resin and fiberglass. When I finally finished, it was hard and smooth. No soft spots. The last 4 layers of resin was colored black. It actually looked good.
May 2023, the entire fiberglass patch is gone. All that's left is the bondo and its chuncked out.
At this point, I just want the damn thing fixed without spending $20K. It doesn't have to be polished fix, I just want it structural sound, safe and water tight.
I have attached a bunch of photos of the damaged area. Hopefully, I can get some expert advice on my next attempt at repairing this area.
