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..

I've tried the gutter seal product and I hated it. It didn't "wick" into the seam at all like it was claimed, and it skinned over immediately so it was impossible to tool. I removed all of it that I used and replaced with gray sikaflex.

I suggest getting a plastic syringe and filling it with sikaflex or dicor to shoot into the gap, then seal around the perimeter with the same product.

The higher your expectations the fewer your options.
