Alright I have been getting some help on my fender fix and still need to fix the crack it left in the boat. It hasn't been a week since my boat has left the boatyard repairing the same thing on a much larger scale (1" wide by 4' long) and it makes me sick to have to bring it back for another costly repair. Due to where the crack is I am not worried about the look but just don't want it to get larger. What are my options? The crack is only about 3/4"long and 1/2" wide this time. Pic for reference.
