Question regarding Windsor Ontario built cars (70 Swinger)

Thanks for the links, that's great info! Do you think the grey was a sprayed on process? I'm only wondering because if it were dipped it would be where all the black appears to be.. Mainly behind brackets and in the seams with no evidence of the grey sealer.

Dan, could you take some pics of your car when you get the chance? I wish I had a piece of the underside to get colour matched.

I will take some pics tomorrow Randy, there's not a whole lot left but I will give it a try. Can't tell if it was sprayed or dipped.
