...Bondo has no place on a boat; much of this is poor adhesion often to the old glass...
I agree completely. I’ve never been a bondo fan.
I’m wondering what boats have this and why. My boat is a 1999 and I’ve noticed that Sunbeam (2002) has bondo over the keel as well.

Does anyone know what the purpose of the bondo was?
I’ve been puzzling over this and I’ve read of a water leakage problem in some C-Dorys that was caused by the brass keel strip screws penetrating the hull. Is the bondo an attempt to solve that? Maybe someone at the factory thought the screws shouldn’t be shortened so that area needed to be thickened, and dumping some bondo there was cheaper than laying up more glass?
This is all my speculation of course, but the bondo is over the keel area and it appears to extend from the tip of the bow (I haven’t removed all the foam to verify this) all the way to where the brass keel strip ends. In my boat the bondo stops a little more than a third of the way back from the forward end of the toilet storage area.
Is this where the moisture under the foam in my boat came from, through brass keel strip screw holes in the hull, eventually traveling under and through the bondo?
I’m wondering if I should grind/chisel/peel away all of the bondo over the keel and see if there are screws penetrating the hull. If so, then remove them, fill the holes, thicken the area with some epoxy filler and fiberglass mat, then remount the brass keel strip, being certain that the screws don’t come close to penetrating the hull.
