    Two half molds with matching flanges. Layup and trim each half, then put back in mold and bond together using the matching flanges of the half molds to align everything properly. If you have enough space you can also add a core.

    You can shape the spoiler in foam and then layup the 'glass on the outside and then sand it smooth. That is the easiest way if you don't have the molds.

    Hello, be sure that if you make a sealed "two part" fiberglass spoiler that you also drill a few quarter inch holes on the underside between the pillars or somewhere not seen as well.

    reason being, if it is sitting in the sun, an interesting display of expansion will take place and if it doesn't just balloon the part it will eventually rupture it in a less interesting display of two parts...

    have fun with your project !!
