Review: Came soft and ready to glue in wet area (shower in boat) - Worked as advertised I have received flex glue that was unusable as it was hardened. This was good to go! Fresh and soft and sticky and waterproof. It only lasts a couple years in the sun But I just do it over every few years. Pretty good if you need it to stick in not perfectly dry or clean conditions. Pretty much worked for me. I use it to keep water out of seams or joints etc ## Features - CAULKING GUN REQUIRED FOR THE 10oz.
