Default Body Panel question

I am stripping my 75 in preparation for paint and found something curious on the left rear quarter panel. In the photo below, what is the dark area where the bonding strip runs? This was entirely under the red oxide primer so I assume this was from the factory, or some damage occurred, was repaired and when repainted, redo oxide primer was applied before repaint. If from the factory, what in the world? The area is entirely smooth and I can feel no discernible edge or transition from fiberglass panel to the dark area. As always, I appreciate any and all responses.

Thanks,
Bryan (BEJ)

Clearly it is a repair, it is just that this particular repair looks like nothing I have seen before. Also, given that it was under the factory redo oxide primer, was this a repair done at the factory? Looking at the back side of the panel, the bonding strip is there and looks completely undisturbed.

Who knows? I've seen a couple of corvettes over the years that had never been damaged but had repairs evident from the factory. Stuff happens, even to the manufacturers.

And it appears to be a nice repair (from what I can tell by the pics) so in the big scheme of things does it really matter?

Make sure you get it level and blocked and get on with the finished product.

It is a very nice repair. My questions are more curiosity than anything else. In the grand scheme of things it isn't something that I'm wringing my hands over and ultimately I will just move on from it. It just struck me as a peculiar looking repair and odd to be under the primer.

FWIW, and to elaborate more, I've seen repairs on "new" vehicles more often then you would expect. 99% were done nicely and correctly.

Just be glad it isn't like some of the older vehicles in years past that actually used lead filler between the roof and quarter panel. Makes one heck of a mess and a surprise when you hit it with a grinder .........

Well it looks just like Vette Panel Adhesive which you can use as a filler. All of my dried VPA looks this dark grayish color.

But as far as I know they did not have VPA at St Louis, so either the red primer is newer or maybe this is some dried OEM adhesive. I have used Ecklers Restoration Formula body panel adhesive which is "supposed" to look like the OEM adhesive and the Ecklers stuff dries to a grayish black.

This sure looks like VPA to me though. Nice repair.

Interesting. The saga continues. Clearly something bad happened in the left side of my car. While removing the red oxide from the left front fender I found one spot of the Orange flame on top of primer and more of that dark grey repair material. Makes one wonder if the car was damaged after paint and was sent back fir repairs and repaint. Who knows? One thing for sure is that this fender has a lot of filler to be removed.



The spot of paint was as large as the white area but some was rubbed off with the scouring pad.

Curous question, does anyone know what type of hardness testers they use when manufacturing the bodies?
