Windshield Frame Caulk ?

[black_k5]

Hi guys, I just bought my first k5 a few weeks ago and Im starting to work of some of the things the previous owner did not do correctly. So the guy owned the truck since 1992 and said he never had the top off. I found this to be true when I took the top off 3 days after owning it and found the paint was a different color under the top and he had it caulked on there tight. So my question is when I was trying to get the caulk off the top of the windshield I though there was bond under it so I took it all off. Now I'm starting to wounder if it was a factory body caulk? I tried to attack a picture of what it looked like while scraping it off, I'm new to the forum so no sure if it will work. Thanks
