In my world thhis boat is called a Windrush 14.
The gel coat will come up like new. Just take the stickers off and replace.
Prob with the fittings is often that the boat has become sloppy and a lot of people glue it all together. This could account for paint around or on the joiners at the beam sections. This boat was made to transport on car roof racks and once the big screws are loosened the whole hull flops inboard.
Don't paint it!!!
