What is the difference between fiberglass and poly-urethane body kits?
The difference between fiberglass and poly-urethane body kits is that they are made from different composite materials. Poly-urethane and fiberglass have both positive and negative qualities. Urethane is a rubber-type material that is very flexible and durable. However, it is more expensive than fiberglass. Fiberglass body kits in general are less flexible than urethane body kits (although this definitely depends on the manufacturer), but are more resistant to extreme weather conditions. Also, paint adheres very well to fiberglass, so there likely will not be paint problems with fiberglass.
