A little FYI from industry manufacturer

Currently DF only makes fiberglass, because that is the only suitable material for car application. Fiberglass is very strong and semi flexible that can hold its shape and form throughout decades of extreme temperture use. If you have seen our fiberglass it is no way to be compared to any other company. Our materials alone cost more then the competitors entire process to making their products. The material used to make one bumper at our bulk purchasing price from our supplier is approximately $175. We use US and European materials. Hexcel fiberglass, the same stuff used by Boeing. Our resins are tooling grade which offer low shrinkage and high strength. Our raw materials are all certified per lot. There is no such thing as Grade A or double AA CF. Either the CF is certified to use for Aerospace or not. There is so much lies out there, there should be laws against this. There is no such thing as color CF, Carbon is black and you can't colorize black. Those color CF they sell are colored fiberglass such as silver, yellow, red, blue, gold, black (which they sell as CF). Don't buy into the hype of flexible fiberglass, all it is, is nothing more then just adding an urethane agent into the resin and mixing it together. This urethane agent will cause the bumper to warp after curing. So out in the heat it could change shape. If you flex the bumper too much it will crack the gelcoat paint. When that happens it will spider crack your paint and could lead to the paint to flake off. All the big companies are now manufacturing kits from China which only cost $15 to make a bumper and retailing from $150 - $475. Just imagine the quality of the materials being used and the standards.

We have contemplated about going into the urethane market before, but however the technology for urethane is far from perfected. Urethane has a short life and is a very heavy rubber based material. Many manufacturers are using urethane because the material is cheap, the machine needed is cheap, the molds are cheap to produce. There is only one company in the USA that make somewhat decent urethane and it is Kaminari. JP also make good urethane from Japan. They actually have a high pressure machine that can yield a thinner and lighter part. However as all urethane material do not have a long shelf life and paint does not like to stick to urethane as well by nature. The constant contraction and expansion from the weather temperture causes the material to stress and eventually give out. The material is very sensitive to tempertures from 60 - 80 degree F. This is why all bumpers will sag within 3 years or less. The thicker the part the more it will be affected by temperture.

When we expand and get into plastics, we will be offering actual OEM thermoplastics. Our bumpers will weigh 1/3 of urethane, and will not be affected by tempertures. Car paints stick to polymers much better and are easier to paint. A typical Urethane mold for a bumper is $6,000.00 where as a TPO Polymer mold is $250,000.00. It is nowhere in the same ballpark.
