the rusty one is cool, thou i think that the rust is on places where it should rust at a later point, so i mean that, you should have the holes in the hood, have it without holes, and just place a layer with the car paint to ground paint to rust to holl.

But i don`t think you should have holes in the hood, on the edges is where the holes start first.

If somebody has more knowledge please do reply here, i could be wrong
