Sorry I meant attribute to that scoop to Bob, got some names mixed there.
Mike, it would seem there were only two different facilities that came to paint these.
Fram first painted some, and then farmed the procedure to a vendor more capable of quality finished product.
NAP would seem the logical one because they were 1/2 hour away, and already set-up and using argent.
Problem is thats nearly 40 years ago and not many ex-employees around to get answers or who would even remember.
I may be missing something here but where is the picture Scott shows of the underside overspray.
Are his pictures not of a bare scoop before anything was done.

Ohhhhhhhhhhhhh! thats a nice one

Thanks Mike....I've got a bunch of pictures of undersides, NOS and used, but they somehow grew and I need them downsized to post them...I used to know how..

Terry and gang, FWIW. I restored an original red painted bubble last year, it has original paint when I recieved it. It was badly damaged and needed significant repairs so it wa stripped. It had only the red oxide primer under the red paint, no gray sealer. Sorry no pics.

Also not mentioned on this thread is the over spray patterns on the undersides. The methods used to primer/seal the bubbles involved hanging them on hooks bottom side to bottome side like a big clam, front of the scoops towards the ceiling.

Since the holes the hooks passed through were off center the two bubbles overlapped [Edited by Moparts - Keep it clean] eyed just a little and masked one another from overspray but not entirely due to the slightly [Edited by Moparts - Keep it clean] eyed offset. You can see this patern quite clearly on the upside down samples posted above. So, if you want to paint a bubbe to abslute OE perfection you'll need to simulate this process to get the over spray patterns right on the underside. Of course being painted at two different facilities likely varied the outcome, this prcess may not have been used at both but I'll bet it was used for the majority of them as every one I've seen other tha the red one looked that way.

*The NOS example shown above was painted differently than every production line unit I've seen, most likely primed and painted using a different process

The scoops were hung from the mounting holes on the outer side of each drain hole opening, probably facing each other as mentioned.
That is where you see a gap in the primer/sealer

As Terry posted, here's a marked up example. The red lines point to the bolt holes, it appears that one or the other was used to hang the bubble, not both at once (guesswork, it might have varied). The blue arrows point to areas of over spray that indicate which part of the "masking" bubble was overlapping, the arrows point at "stenciled" areas which are the same shapes of the holes in the masking bubbles flange (gray ovals and such) the the drivers side bubble bolt boss being mostly red indicates a close connection of the two parts when the grey was sprayed keeping the flat surface free of gray sealer. The side which is pretty much clean is unusual as Mike pointed out, I guess that particular bubble overlap masked it off fairly well is all. The free hanging bubbles moved around a bit as they were primed so the red and gray coverage/over spray pattern usually varied a bit between them. I have more (clear) pics of this on other examples I can post if needed.

I could be wrong Scott but it would appear both holes were used at once so as to keep the scoops balanced against each other.
Here is a shot of the other side of the same NOS scoop with the break indicating hanging location, thus one on each side of this one.

Regarding the red scoop Scott mentioned having only red oxide primer on it, here is a shot of the underside of one.
Only red oxide primer showing, no grey sealer.
This would in all probability be one of the first scoops.
Notice no break in the primer for hanging...done by hand in a booth perhaps?

Regarding the hooks Terry, I woudn't doubt it a bit, it's even more likely that it varied depending on the guy doing the work. I wouldn't be surprised to find that some were hung from the drain holes rather than the bolt holes as well, some of seen looked as if that were the case. Here's a pic of a red one (not the one I restored), it looks to have just gray sealer but hard to tell, I was told this is original paint but I can't confirm that.

This is a 71 production line piece (it was a black Organosol bubble in original paint). Looks like two hooks hung this one as well.

Another original production line 71 Black Organosol bubble

Interesting pics Scott.
Regarding the underside of Chris' scoop, I have never seen an overspray pattern like that underneath one....looks like someone got trigger happy.
That one was in the trunk of E-body in Tennessee where it had been stored for years, and it had come from MI before that.
It may have been tweaked along the way.
Here's a picture of one that I mentioned earlier having been painted red at Fram initially and then argent over top.

closer shot of the red under the argent....This is untouched since 1973 when the shaker hood and complete assembly was purchased off a sassy grass 383 Cuda wreck in a yard in upstate NY....$175.00 for everything...those were the days

Guess if i had to spray a 1000 of them a hanging system would be the way to go, but it sure looks like a lot of inconsistency from one to another. (yes i have never done one that way so guess mine arent "OE" correct, except in colors, The one on the left is an untouched NOS black scoop)).

One more thing to add to the issca (??) judging standards.

I wasn't pointing fingers concerning your work meeting OE standards Mike, (hopefully you know I've always given your work high praises) just trying to get them to the next level which it appears to me there is a little room for.

As far as ICCA "standards" there are none really, it's an ever evolving set of guidlines which changes as new information is obtained and added. In the case of the details on the undersides of Shaker bubbles, yes, they are scrutinized by at least 2 judges and decisions about correctness are made.
