Repairs all types of wader fabrics and materials including breathable like Gore-Tex and more, McNett's Aquaseal provides superior adhesion, wear resistance, flexibility and waterproofing. Perfect for waders, rain jacket, float tubes, and more, Aquaseal's highly-concentrated formula provides thick, long-lasting repairs with minimal adhesive shrinkage, and since it remains flexible after curing, can be stretched and folded without damage. Great when used in conjunction with a fabric patch applied by itself, Aquaseal has proven handy not only for repairing leaky fabrics, but for smoothing and strengthening spliced shooting head fly lines and sink-tips too.
