    Are you vacuum molding this or is it simply epoxy rolled/sprayed on?
    I'm laying up the resin by hand, without a vacuum. The key is to use as little resin as possible for a stiffer, lighter part, and to use a roller to force out all the air. Vacuum bagging is something that I'd like to try, but not on a piece this large (and relatively simple). I was thinking that V2 would use clear gelcoat on the surface of the mold, as in I would apply the clear gel coat, then the first layer of carbon. I think it would provide for a more durable outer surface, and alleviate the air problem.

    The tricky thing about carbon, versus fiberglass, is that you can't see the air bubbles through the fabric.

    And as far as the bracing goes, I may just make a mold of the underside of the trunklid, then bond that piece to the underside of the carbon skin, but that would make this weigh more than twice as much.

      that is probably the better and easier way to do it, cus then us normal people can have one too!

        what about if you layed in fiberglass reinforcement bars on the bottom side?

        Something like this (I know about this product from my industry):

        I'm sure you could get it in smaller quantities

        Also, they would be fairly easy to add to the mold after the trunk lid was made. I'll take v1 off your hands -- not too worried about the bubbles -- would paint it brilliantrot to match anyway...

          Dude, these are the types of things I want to see!

          Let me know the next night you're working on it. I'd love to come take a look if you wouldn't mind.
