New bathroom sink replacement bead sealer

[SFVdave]

I am replaceing my bathroom sink and it has a white gooey paste like bead around it making it difficult to pull off. I have it all cleaned up and the new sink ready to go in. What's the bead? Does look like a very soft version of plumbers putty. Can't used Dicor or anything that will dry hard.

Not sure what type of sealant was used, but in the stick house, I've used a clear plumbers putty w/ very good results. Had to scrape off anything left w/ a razor blade 1st before installing sink then the putty.
