    Start by coating your part with mould release wax or HPV (can't remember what it stands for... basically it is liquid vinyl)... once you have your mould release taken care of, coat the part with tooling gel (gel coat)... usually tooling gel is bright orange... the gel coat will pick up your finish texture... if you have a paint-ready final part, your parts should come out of the mould being paint-ready... once the gell coat is cured, lay-up one coat of fiberglass and polyseter lay-up resin... let it cure and then lay up 2-3 more layers of the same. Now like someone already said, you may need a multi-part mould.. this is if your part has compound contours with negative draft... we can talk more about that later... mulit-piece moulds will be tough and not really for a first attempt... but who knows... we don't know your abilities... then again, with your questions, neither do you (not a slam)... sooo... I'll check back after work... have a wonderful day!

    ***Too many pieces and parts to list... maybe someday I'll show'm to ya!***

    Coachreed,

    thanks for a prompt reply.

    I'll let You guys know how it goes. I picked up some plaster today and I'll start working on the mold tomorrow.

    The parts that I am facricating do not require multiple molds - I picked the easy parts first to get things rolling....one has to be able to crawl before running as the saying goes

    Once again, thanks a lot!
