I used this backer rod for sealing gaps around my exterior siding before applying caulk, and it worked perfectly. The foam is flexible but firm enough to stay in place without constantly popping out. It made my caulking job much more efficient and helped me use less sealant overall. Definitely recommend for anyone doing weatherproofing or joint filling.
