Understand, approx 70% of your projects effort will be in getting the mold right. If this is a one item project, you can cut a few corners, problem is, best if one has some experience first before deciding which corners to cut. Not sure if a gel coat is needed here, gel coat adds another complication/cost/step, and it mainly only adds to looks in finished project, and gel has a potential for "alligatoring", which defeats its whole purpose.
Some molds can be fudged as a single mold, by making the mold flexible and/or sacrificial/sectional, or in your case when the plug is the bumper or making the finished part in multi lay ups, a thin layup to be easy to remove from the mold, and then another after pulled from the mold to gain needed ,strength. Risky because you need to somehow maintain shape outside the mold for second layup.
It can be done, but its a learning process.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

I see Unlimited lists them, and they do a lot of bumpers in carbon you might check with them.

I figured if I'm going to spend that kind of dough, I'd rather learn something. I've done fiberglass work, just not made a mold. Being that Unlimited is the only ones to offer them, maybe I'll make the molds for multiple use. Thanx for the input!

STEF, here is a write up from Jay Brown, a friend of mine, and HEMI Joel's, on how he made a mold for his Shelby bumpers. I did the finish sanding and paint on these, and they turned up very nice. http://fepower.net/simplemachinesforum/index.php?topic=3783.0

I'm not sure, but I suspect you are looking to build some higher appearance quality bumpers, so this article may not be what you are looking for. www.midwestattachment.com/hood shows how do fiberglass reproductions by doing a splash over on existing parts. Great for race only,lesser detailed vehicles.Much less expensive, and time consuming as it doesn't require that detailed primary mold. My son and I built a hood (pin on) for our Lancer drag car,with a snorkel scoop. Very pleased with the way it came out.For those of you , like us, with nothing readily available or economicaly feasible, this is a viable option.We have to use the coins where they are best spent or our project wont make it.Hope this helps some of you

With shipping, the Bumpers from Unlimited, would be $480. Not a deal breaker, but $200 just for shipping blows. So, even if it costs me $480 to make my own, I don't care. I get to learn something, I've not done yet.

200$ for shipping is uNsane ! Someone at unlimited didn’t figure that out correctly. Each bumper should ship as though they were 25 pounds each.!PLUS I’ll bet you could send them by TRUCK FREIGHT (terminal to terminal)!for about that kind of money Just talked to Unlimited, apparently UPS and FED Ex, really jacked up their rates for long packages regardless of weight. They said they don't pad their shipping. Is what it is...

He can build it better, cheaper, and ship it for next to nothing, but never does.
