I figured I'd ask Mr. AI a question.

Was corvette yellow weather strip glue in the 1960's originally yellow?

Mr. AI replied

Yes, in the 1960s, the weatherstrip adhesive used on Corvettes was originally yellow. This yellow adhesive, often referred to as "Buffalo Snot", would turn brown with age. While black weatherstrip adhesive is also available, it's the yellow variety that is used for chasing judging points if aiming for an original installation look.
This yellow adhesive, according to Corvette Pacifica, was used by GM originally. Today, you can still purchase yellow 3M weatherstrip adhesive that is suitable for Corvettes from 1953 to 2020.

Far easier to handle and easier to duplicate originality is DAP yellow contact cement. Brush-able,,
In a can, not a tube.

Someone posted this product from ACE Hardware, called DAP Weldwood Contact Cement. I bought it, but didn't use it.
It can be brushed. Maybe someone has tried it . . .

I've never been a believer of the Yellow weatherstrip adhesive. I can't buy into the theory that GM would do such a sloppy job with the adhesive if it was visible when originally installed. With that theory in mind, I have only used contact cement on all the restorations I have done. DAP in the blue can holds the best.

100% agree with you !

This is why AI can't be trusted.

I also agree with Joe and Bob. The discussion was my goal with the AI post.

Dont believe it was yellow but almost clear. Turned yellow then brown years later. Also think it was applied with a dobber not a brush thats why they didnt have to be careful about applying it to the door jam. Had many original paint Corvettes & all had messy glue jams.

If you ask AI the question this way:
Was corvette weather strip glue in the 1960's originally clear and turned yellow with age?

The answer I got is below in green font.

I agree with Harry - you have to be careful with AI...it's FAST, but depending on how you structure your question, you can get the answer you WANT (if you're biased toward one position or another) - particularly if you don't pursue other information.
Ask different ways as has been done here and you can be left with some answers that directly conflict with each other in some way (or at least waffle around the facts with loose language):

Based on available information, it is likely that some of the weatherstrip adhesive used on Corvettes in the 1960s was originally clear and subsequently yellowed with age.

• Original application: Some sources suggest that yellow-colored adhesives were used during the factory application of weatherstrip on light-colored cars around the 1960s.
• Aging: Adhesives and bonded joints undergo an aging process, according to Fraunhofer. Factors like environmental exposure (e.g., ultraviolet rays in sunlight) can lead to changes in the adhesive's properties over time, says Kejian Polymer Materials (Shanghai) Co.,Ltd. It's plausible that adhesives initially appearing clear could yellow as they age and are exposed to the elements.

It's important to note that adhesive technology has evolved considerably since the 1960s, and a variety of adhesives with different compositions and properties were likely used during that era. Therefore, while yellowing with age is a probable scenario, not all weatherstrip adhesives used in 1960s Corvettes would necessarily have been clear initially.
