gutterseal, sikaflex 221 or both?
After removing centimeters of old caulk my vent is ready for re-sealing. In the seam is still some flexible material available - see picture. My guess putty tape?? Removing and re-installing is not an option as there are about 50 Rivets!
Reading this forum I though of re-sealing in a two step approach: 1) fill interior of seam with gutter seal 2) add add a second layer of sikaflex 221.
Can you use these products together or do they negatively interact with each other?
Thanks for your advice..
