When you say tagged a corner...is that the side wall or the fiberglass end cap.
If it's the end cap, a fiberglass boat guy should be able to make a repair that is invisible to the eye.
If the side wall or the roof is involved, not sure they would want to get involved. While the side walls are sort of fiberglass, they are different.
FYI - While I understand the response, silicone slopped on may be an issue. Near impossible to remove all traces of it and nothing sticks reliably to it. Just throwing it out there in case someone else has a similar incident.
