The hood is plain plastics, any good plastic glue is going to work just fine. Mine cracked, my friend cut open the crack using a die grinder with a really thin blade and added plastic glue, glue was charcoal in color and it got rock hard when hardened. He taped the outside of the hood make a smooth surface on the outside and on the inside the grinded down the excess, then sandes the outside of the hood, added primer and repainten the whole hood black. If you are going to use fiber glass and polyester resin make sure you grind the inside of the hood with a rough grit paper, like 60 or so, tap the inside with a sharp object to make grooves for the resin to stick to as it will not stick very well to a flat plastic surface.
The side covers are a whole another story, this kind of plastic can be plastic welded (the hood as well).
