Question regarding Windsor Ontario built cars (70 Swinger)

I interpret it as the body was dipped in primer to 15 inches to get complete under car coverage, and the rest sprayed on and then baked dry prior to paint. So it would make sense as to what you're seeing as primer.


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.
