I believe that the core support area was sprayed before any of those items were installed. This is of course is a 72 Duster,but you can see in these pics of my untouched parts car that their is no over spray on the wiring,hood latch mechanism, or the sides of the radiator. my not be seen here but on this car you can tell that the lower grille support which is body color was on the car during the black out process. this car also shows that the car was about waist high and moved from side too side to create coverage. Pay attention to the lack of over spray on opposite sides of protrusions to get a feel for which direction it was sprayed.
