Where it's just globbed on like that, don't be afraid to cut it down. You can either make it look better, or replace it yourself. After a few years, most of it breaks off or separates anyway.
I replaced most of mine with more expanding foam, then shaped it and covered it where I could with gorilla tape. Works much better at making a real seal.
