i want to design a custom front end for a nx 2k and i was wondering what kind of stuff they use to make those bootleg ass looking front lips on some cars, i plan on creating a 3-d mold then puting that stuff over it to mold so i can fit it over just to see how it looks, to see if its worth getting made, so any help u can give me with materials to make a thin shell after i make the mold would be helpful
