Positraction Caution Label

[Edgemontvillage]

The positraction caution label was originally printed on non-adhesive backed, non-coated paper and applied to the underside of the trunk lid with glue. From what I've seen on Gen 1s where only glue residue remains where the label once was (often the case), the glue appears to have been applied in a cross or X pattern and rarely provided edge-to-edge coverage or full label adhesion. Its been suggested the glue was applied in multiple dabs however that's unlikely in high-volume production lines like Fisher's where economy of motion and effort is the standard. Based on the glue pattern in the photo below from my project, its also unlikely that a roller applicator was used but possibly a large sponge or mop-head style applicator or? The glue, I expect, would have been non water-based (due to recurring condensation on the underside of the trunk lid) and shows a semi-transparent off-white/yellow color (how much of this is age related?). I'd like to duplicate this glue and application technique for my project and would appreciate input on currently available glue products and applicators that would produce similar results to the original.

Kind of also looks like figure eight or clover patterns to me.

 That looks like 4 round dabs. I wonder if the same applicator and method was used for the tire pressure decal application? 
Was the tire pressure decal also applied the same way?

Mike, I assume you meant the Jacking Instructions? These didn't generally suffer the same fate and seem to fail less often (from what I've observed anyway). They were adhered better (differently?) than the Caution label. Members have posted on how the paper shrinks on these JIs leaving residue as they recede however they hung on!

my car has the factory original under-trunklid jacking and positraction labels; I think these are 'protected' from sunlight/rain/etc by being where they are.

The Tire Pressure decal was affixed to the back of the drivers door for 69, and mine was 'missing' when I bought the car in 1976, so I can't comment on that (although I'd love to see some photos of factory original '69 tire pressure decals!  (note my car is a mid Sept '69 production so it does still have the VIN decal on the rear edge of the drivers door, so I don't know why the tire pressure decal was missing, but the door decals were not as 'protected' as the decals under the trunk lid.

Thanks for posting Gary, as the Caution label on your trunk lid is still affixed its not possible to see the glue pattern however does the residue extend beyond the edges of the label? In the photo it appears that it may?

The corvette plant used a brush to apply the yellow glue out of a can for the door and hood seals.
Pretty sloppy in a lot of cases, IMHO the posi labels appear to exhibit the same "sloppiness".

Does anyone know the caliper (thickness) of the original label?
The ones I have had in my hand feel like Postal return card stock which is .007-.009- (copy bond is .003) - postal return cards are high bulk - but low weight (meaning they are thicker than their basis weight would have you believe)

The glue does *appear* to extend beyond the label in some places.   I'm under the impression that they were hastily slapped on over some glue, or perhaps glue applied to their backs and hastily slapped on the underside of the trunk with little worry about 100% adherence or appearance (after all, they are applied to the underside of the trunk lid!).

IF not mistaken someone said the glue was neoprene glue - the same that was used for the foam triangles on the wiper cowl vent and what they brushed over the raw metal exposed when the VIN was stamped on the cowl top.

I believe this has been discussed before, and I believe I might have posted a pic of an original sticker that I removed. If I can find it, I will provide the link.

I agree, hastily applied with no set pattern of glue application.

So far I can’t find what I am looking for, but I found this.

Thanks Bryon, I wasn't able to locate those posts. Based on John H's (JohnZ) posts regarding both the Jacking Instructions and Caution label we know why they differed and how they were applied. To summarize:

Caution label: Glue (water-based, yellow, muscilage type) was applied with a small roller.
Jacking Instructions: Printed on adhesive backed paper.

My X77's label is missing, always has been since I bought the car in ;73, but the glue is still plainly visible on the deck lid, a solid bead much like what comes out of a latex caulking gun. applied in the form of a loop on the right underside of the lid. Really sloppy job, probably why the label came off. Definitely not roller applied -

Steve, is your Camaro Van Nuys or Norwood built? Please post a photo of the Caution label adhesive residue from your trunk lid.

Lloyd - thank you for finding the muscilage part that makes sense why they fell off so often.
