One of the most common asked questions is about fiberglass quality.
Know as well like FGRP, often the people think it´s just bad plastic, really far from truth.
When discovered, it was a really fast revolution and until the carbon fiber arrived, it was the better material available due to its lightness, strength, impact absorption, weather resistance and the easy to work with, putting it over steel, aluminum and other complex materials.
Today, the production process is much more expensive than steel, aluminum or abs plastics, due to need good professionals with high skills, this is why it´s not common on street cars, but by described properties, it’s the most popular material in race cars around the world, been only better the carbon fiber, but at higher costs.
Just an example, the body of one of the best cars ever, the Ferrari 288 GTO, was made in fiberglass.
