- Acrylic caulk: It is simple to apply and works quickly. However, it is unable to repel moisture and may crack or shrink when exposed to the elements.

You may apply a larger bead of new caulk, which covers the previous bead and adheres to the uncaulked surfaces on both sides. Clean the surface of the bead and surrounding regions with rubbing alcohol to get rid of as much grease as possible. Test a tiny area with the larger bead of caulk to ensure it adheres properly (If oil is remaining on the old caulk, fresh caulk won’t cling). Apply a larger bead of new caulk using a caulking gun, ensuring it adheres to the surfaces on each side of the previous caulk.
