Perfect product
Self leveling and does the job of sealing up things up with persision. This is my go to for handyman projects

This stuff is amazing!
Nice consistency when applying, and drys to a hard by flexible seal. This caulking seems to be able to plug leaks in my pergola gutter better than anything else.

Works great
This stuff works great on gutter seams. It’s made by Henkel, so I would expect it to do what it says. Just make sure to clean the aluminum before applying.
