    Building Corvettes: Body and Paint

    The process of assembling Corvette bodies and painting them is probably the most labor-intensive part of the whole Corvette assembly process. Plus, it's where the real art of Corvette-building takes place. The rest of the build is pretty much purely mechanical. As we know, the St. Louis Corvette plant was very limited space-wise and also a pretty decrepit facility from the get-go. That's more-than-likely why Chevrolet outsourced a lot of the body production during the C2 years when, due to much increased popularity of the cars, production numbers took a significant jump over the C1 years. Some say that the outsourcing of much C2 body production to A.O. Smith was the result of some sort of "reward" to that company for some other "favor" they did for GM. I kind of doubt that, though. For one thing, I doubt that A.O. Smith would have considered this kind of low volume production work very much of a "reward". For another, there had to be something in it for GM and I think that something was related to a recognition that the body shop at St. Louis was not capable of handling the increased production and doing it in anything like a quality manner.

    The thing I can't figure out, though, is why they did not continue this into the C3 years? C3 production went way up with a peak of almost 54,000 cars during the 1979 model year. This was almost TWICE the number of cars built during the 1966 model year, the highest production year for any C2 (and half of those bodies were built by A.O. Smith). The quality of Corvette body and paint work, always pretty marginal, notoriously suffered during the C3 years as we have discussed in other recent threads. I have no doubt that this was due in large part to the inadequate facilities and capacity at St. Louis. So, if Chevrolet ever needed to outsource body and paint, they needed to do it in the C3 years. But, they did not. I wonder why? Maybe neither A.O. Smith nor any other firm wanted to do it?

    Joe -

    I'm sure that the 4-month strike at A.O. Smith (August 31, 1966 - January 9th, 1967) which forced Chevrolet to run the St. Louis Body and Paint shops 12 hours a day six days a week left a bad taste in GM's mouth for any further outsourcing of bodies; in addition, the original plan to move Corvette production back to Flint had been abandoned in 1966, so there was no longer a strategic advantage to having a body source already established in Michigan.

    Chevrolet never invested a dime in the Corvette plant that wasn't absolutely necessary to avoid loss of production, so they just continued to increase the line rate as body panel adhesive cure-time technology improved and continued to crank them out as fast as they could; whether the facility itself had adequate capacity to accommodate that volume wasn't a consideration.

      I remember a 1971 [i]Corvette News[/i[ story about how improved the 1971 Corvette body was over previous years. It admitted that "pops" in the fiberglass during the paint heat curing had been a problem, but they claimed they had solved that issue by 1971. Now about this bridge I have for sale....

      It was an interesting story with many photos of Corvette body work including pictures of the lay-out of LT1 stripes.
