Hi. I use the flexible resin on Ballistic nylon to create a waterproof flexible seal for skin on frame sea kayaks. I use this product since my previous supplier discontinued their product. I am happy with EF80 in general but I have found that exposure to water in some instances tends to result in a milky discolouration that disappears once the hull dries off.
Is this a normal situation? I produce the kayaks as a professional boat builder so am concerned that the product is not actually suitable in the long run.
