i have a gen3 hemi powered dodge dart(1967) and i am wanting to make some carbon fiber stuff that nobody in america produces or willing to produce unless a rediculous amount of money is offered.  then they charge double that.  so in saying that.  i would like to make some carbon fiber stuff and see how difficult or simple it is or is not.  i am quite hesitant as it seems quite intimidating when watching videos of others doing molds.  

making the molds does it destroy the part used?
how many times is the molds good for?

is the molding materials difficult to obtain?
