I was wondering what the underside was sealed with from the factory? Mine appears to be black (the same stuff the body was submerged in half way up) I have seen one other 1970 Swinger (Windsor built) done in the grayish blue sealer pictured below, but I'm unsure if that's right? Did they dip the cars and then paint them grey underneath with sealer afterwords? My roof had the Original paint on it and it was done in red oxide primer over the bare metal, then a bright green sealer and then the Hemi Orange.. It appears to have no grey sealer anywhere??

I am recreating the factory overspray look under my car and want to know which is the right look. This is a sept 1969 built 1970 Swinger 340




This is under the factory undercoat.


Here is a car that was restored (Windsor built 1970 Swinger 340)
 
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 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.

PPG has been the paint supplier to the Windsor Assembly plant since the early 60's and they still supply the plant today.

I never worked for the "Glass Company" so I can't answer your question with 100% accuracy.

I did try to find out the Windsor Assembly paint processes used back in the 60's and 70's but I was less than successful. Seems my PPG contacts have all retired and moved away.

I can tell you that the "autophoretic" processes had come into being around the time your car was built. All the major OEM paint suppliers used a form of it. It's a pickling process/dip coating process that preceded the e-coat processes that are used today.

Primer and topcoats were hand applied. Poorly too, I might add. A crude chip coating may have been applied to the lower portion of the body but I can't verify that.

Body sealers and sound deadeners were made up of off spec primer and top coat components so the color varied batch to batch.

If you have any additional questions PM me and I'll do my best to answer them.

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.
 
I just dug thru some old pics and found a pic I took of under the gas tank before I sandblasted it and it looks black to me.. With orange overspray.

Danny, let me know what you find under your gas tank when you remove it.
