I have a 70 SS and recently found my build sheet during replacement of the carpeting. I removed the backseat and found the buildsheet. It was on the back of the seat with the hogties going through it. I was a very happy camper and took pictures before carefully removing it!!

My question is, what is the best way to preserve a buildsheet while maintaining its value??

It is in pretty good shape but is beginning to come apart in some places. It also has the usual rust colored holes in it.

Is laminating it the way to go or do you just place it between plastic sheets??

Any help is appreciated, thanks Stein..

Mine was laminated by a previous owner, and it's held up great.

I take a photocopy to shows - I actually have an SS that's REALLY red w/black stripes...

Buy a cheap picture frame with glass in it. Then you can hang it up in your living room for all to admire. Just kidding about the living room, but they look cool framed.

To truly preserve the document, one must adopt the archival approach used by museums, et al, for the preservation of historical documents. A quick trip to your local custom frame shop will show you how pricey that can be.
As a professional artist and former frame shop owner (still own the shop, but only do work for myself now), I can offer these tips.
Don't laminate your Build Sheet. Or anything else you want to keep for that matter. Most laminating material out there is not acid-free, and in time will discolor, crack, dry out, and destroy the item being laminated. It is not removable. Sandwich the document between two pieces of acid-free archival paper (readily available at art supply stores), and store it flat in a clean, dry, place.
If you want to display your build sheet, I recommend matting and framing. Use only acid-free matts and backing material. You should never sandwich a document against the glass in a picture frame. Although many, many people do this, it does not allow for adequate "breathing" and is potentially very harmful to paper. A matt provides the standoff from the glass that you need. Remember to cover the back of the frame with a dust cover and never display the item in direct light, natural or artificial, for extended periods. Avoid plastic document sleeves at all costs.
Hope this helps a little...

Strange... I've had my original buildsheets out of the car for over 10 years now in plastic sleeves and stored in a very safe place away from heat, light, moisture, etc, and absolutley nothing as far as I can tell (they were slightly discolored & yellowed when I discovered them - typical condition that these documents are in) has changed a bit. What's up with that?
