John,

Its hard to say. The way that this car seems to have been done was that the undercoating was done prior to ceratain things being installed such as suspension and drive line. The axle bumps appear to have been installed prior to the undercoating as there is undercoating on them. The drive shaft hump also has undercoating completely on it also. The hangers and shackle areas appear to also have either been taped off or had some kind of template on it to prevent the undercoating from getting onto those mounting areas. I will try to post more pics of these areas if I don't have to resize them.
