Aquaseal FD is a clear, waterproof urethane adhesive that comes in a handy 0.75 oz tube. After it cures, it becomes a flexible, rubber glue that is ideal for fixing outdoor gear that’s in constant motion. It also offers excellent abrasion resistance, making it a great seam sealer as well. We use Aquaseal on all our guide waders and it holds up amazingly well. Bonds permanently to surfaces and dries clear. Made in USA.
