It isn't very difficult, but time consuming, the hardest part is going to be matching the paint and clear coating it, you will need to feather the paint and clear coat into the rest of the front cap. I would search on the internet for patching fiberglass cracks. A good link to look at is "http://corvettes.about.com/od/restoration/ss/How-To-Fix-A-Crack-In-Your-Corvettes-Fiberglass-Body.htm". you don't need all the tools like the long sanders, a small hand sander will work for what you are doing. If the crack goes all the way thru you may want to reinforce the inside of the wall as well or the crack may come back. There are many other instructional videos online to show you, I would just make sure to give yourself the time and patience to do the job correctly, otherwise you will be frustrated if the cracks come back.
