you can use the fiberglass repair kits they sell at walmart. it is EASY! I do alot of fiberglass work on body kits and hoods and all kinds of other crap for friends. Its cheap and works great. I sugest you use the right amount of catalyst or it will either A, never harden or B, set up too fast to work.... Make sure you degrease the area very well under the hood and do your repair on the bottom and build a layer or 2 or more to build structural integrity. sand the top where the spider cracks are and if they are kinda deep under the paint, use a glazing/finishing putty to fill in the grooves. Sand and clean and prep very well for paint... G/L!
