west marine makes small patch kits and any marine store would handle
kits allowing you to do the work yourself -be sure to rough up the old
fiberglass with about 80 grit sandpaper and clean the wound with a
solvent before applying the patch. the kits come with premeasured
resin so you get the ratio right and a small amount of cloth allow
curing time some primer and paint will hide any damage that may have
been done - west marine web site will also have instructions on
repairs
