The Pontiac arrowhead found on the front of the 1967 Firebird 400's was the first use of a solid urethane product, also created by GM's Inland Manufacturing. When people see a 1967 Firebird 400, they think that emblem is some cheap repop because it's painted silver and black, it's not die-cast or chrome to match the chrome front bumper, but that's how they did them. The designer of the material said it took a long time to develop paint that would stick to that emblem. It had to be able to withstand heat and cold, and the occasional 'bump' into a pole, without cracking the paint.
