Body sealant at fender/cowl/firewall/ What is it

The is this funky sealant that is deteriorated when I pulled the fender off to repair it and the WW tank.

What is it and what should I use to replace it?

( The Black is POR 15 I put on to prevent rust as a test)

I used the 3M Dynatron Auto Seam Sealer. It's good but not as good as OEM, and I almost destroyed the can getting the lid off.
