You can go to auto parts store and get a kit, or go to a boat repair shop that does fiberglassing. There are videos on YouTube that show how to repair fiberglass, please watch first if you have never worked with fiberglass before. Sorry for your accident, kinda makes you want to cry!
Mr best friend backed in to a tree limb and poked a 6" hole in the rear cap, took about four hours to fix, most of which was letting the fiberglass harden.
