Just got a 76 with 4 speed manual and L82 and supposedly 66K miles on the clock in pretty good shape. Boy I am happy!
While poking around and making a list of stuff to do (this list always gets longer when you get the car home and up in the air, eh? ), I found the gas tank build sheet stuffed up in the rear bumper. Wow, it did not blow out on the way back .
Anyway it is pretty dusty and extremely hard to almost try to read.
Any ideas or Sherlock Holmes techniques on recovering or at least getting it legible?

In my job we use UV and IR scanners to find the frequency of different materials and chemicals. I have often thought that if we had a build shee we could scan it using variable frequencies to see if we can pick up the area stained by the ink but now faded. Have not tried this technique on anything Corvette related but it would seem to be a reasonable approach to finding the shadow left behind by the imaging ink. What ever you do please do not add chemicals to the sheet, not even water, unless is has been treated to prevent chemicals in the water from disrupting your ink and paper. My advice as a paper guy would be to get it in protected from the elements, out of any source of sunlight, and begin researching the prospects of getting a UV or IR scanning source.
Without taking away your original post I guess I should ask forum members if this is something they need, that is, the ability to scan the sheets without damage and see if the data can be recovered.
Over on chevelles.com there are several ways to get to read the build sheet using a cleaner called "acusol" not sure if that is the way to spell it but they have used it to get the tar and crap off that you would find on the sheets when they have been on the floor. The uv/if might be the way to go when we got ours of the 72'ss you could just barely read it and i am sure that some of the ink came of as we used a fine artist brush to clean the dirt/dust off.
Good Luck wro87
Much thanks, my build sheet is very dusty, you can lightly dust it, but it is very fragile, so I am afraid to do too much. It appears to me that dusting might rub off the ink.
Right now I have it in a manila envelope inside. I think the gas tank was replaced and the whoever did the work stuffed the build sheet in the bumper for future use.
I would be happy to pay some kind of reasonable amount for a recovery if anyone has a source. I will check out the second post on aucusol.

If you already have it flat try using a very soft makeup brush from the wife, or cosmetics counter at a CVS type store. Like the ones the CSI guts use when dusting for prints.
Good luck , Glenn
Would photo-copying it work? Or at least make it more legible?
Photo copying does not offer the quality of reproduction that a scan will as suggested above. I always recommend scanning a build sheet for preservation purpose and especially before doing any treatments, lamination, etc. SCAN, SCAN, SCAN.

If the paper is stiff it means it is very dry and the moisture content has been driven out of the paper. You may want to place it between two corrugated or paperboard sheets to protect it from bending as it will snap like a brittle twig unless it is rehydrated to bring up the moisture level slowly. Scanning uses visible light and may pick up some of the details but if the ink has faded then the pigment is gone, but the chemical footprint may still be in the paper.
Forensic services are very expensive and most of them destroy the sample so be cautious about claims.
I am checking now with the forensic photography group I work with to see what, if anything, could be proposed about build sheet recovery using variable wave length scanning and phtography. If the wavelength of the original pigment can be found then we can get a photograph of it using light not visible to the human eye. Hard to explain but let me check this out and see what I can learn.
I'll post something soon.
Good luck with your discovery, wish I had mine.

Severalyears ago there was a post about someone using their digital camera with infrared light to be able to read their build sheet when it could not be read. Don't remember the details.
almost always driver side is where the sheet will be. look from up under the car you may see it hanging over the edge. also you can peek in through the gas tank gasket at the top fill hole once removed.
Not to change the subject. But where would i find the build sheet in a 1980?? Would it still be on top the fuel tank?
I found the one for my 79 folded up and tucked into where the rear strut rod mounts in the center of the car. On the passenger side. Take a look it had to be the same guy's putting these together.
