I used Flex Seal on the fabric covering of a grill arbor to extend the life of it, with excellent results. So when it came time to apply a rubberized clear seal to a new cap, I decided to call Gorilla Glue to see if their product was comparable to Flex Seal's clear seal, which I was assured. Due to the fact that Gorilla Glues are more economical, I decided to buy their clear sealer. What a mistake! After about 2 weeks and after their product initially seemed as good as Flex Seal on first use, it broke down and was all sticky, gooey and a total mess. The result and the word to the wise. DO NOT BUY GORILLA ADHESIVE CLEAR GASKET for this type of exterior application.
