As they said fiberglass is pretty easy to work with. Be sure you cut the pieces you will need before you mix the resin. You will nee multiple layers. Use a small roller to smooth out the air bubbles. The most important part is to protect yourself when grinding and sanding. It is not good for you. If your scoop has a finished flange on it and doesn't need to be blended in you could use Vette Bond or panel bond , the stuff they glue Corvette panels together with. It mixes up like Bondo.
