Lots of good sealants available.
Sika makes several good ones. 221 is a great general purpose polyurethane sealant...great elasticity as well. 505UV for use around EPDM.
Trempro also has
635 as another good option.
I have also used Chemlinks
M1 with good results.
A good polyurethane, tripolymer or polyether should do the job!
