Hi all-so, for reasons I am not going to go into now(unless you really want to hear it!), I have a vested interest in “cloning” the bumper from the 1969 Lamborghini Marzal. You can google it, or see images of it here:
I am mainly interested in what the likely manufacturing techniques were in that period of 1968-1980 ish, in regards to auto bumpers. It appears to be some kind of either fiberglass, plastic over composite foam, or ??? To the wise folk here, if you were tasked with cloning a functioning bumper that would look as close to this as possible, what manufacturing techniques would you pursue? the car itself is a concept car. i will never be able to get into the same room with this actual car, but surely there is some universality in manufacturing techniques with this bumper and others of the era? thanks!!!
