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.

An elevated temperature cure will always help to an extent so if it is possible to do so then I would.  Even if you just leave it in the 30C room for a few days, you should certainly have a properly cured resin by the end of it.
