73 340 duster
Here is a pic of the bottom of my 73 swinger. I was in the process of stripping the undercoating when this pic was taken. Basically they sprayed everywhere from the lip of the rockers in. The gas tank was installed so it would have undercoat on the bottom and straps. The only place it will be thin or not there is in the shadows of things that stick out like the frame rails, etc. It really varies from car to car. I have seen some with large areas that were missed.
