Never used this product before,but i thought i would give it a go as i have 1 pair of waders that have developed the smallest of water ingress around the crotch area. Pair of Hodgmans H5 fitted with in core inners that gave me a surprise last May 2021 when fishing in the River Tweed. After having theses waders for just over a year and wearing them on a regular basis. It was only a matter of time before the crotch area gives up due to all the walking stretching and pegging out to dry. That area takes the most of the hammer due to the material rub. As they are cracking waders i thought it bad form to confine them to the pile of redundant fishing clothing that grows ever larger. Purchased the Aquasure as an experiment and set to giving the crotch area a damn good covering. Make sure you get the folds out as much as possible and use the brush provided. The thin gloves provided. Don't bother, use marigolds. After reading the instructions on how to store. Forget that too. Commit and use the whole tube . That way you should get the repair you require . It takes a hell of a long time to cure and using the whole tube does result in some drips . Depending obviously where the leak is and how your waders are stacked. I have left them overnight and hey ho we have exactly what it says on the tin . A clear , flexible covering . I am confident when the in core liners are replaced and the waders turned inside out. I should be able to go waist deep again without getting wet nuts. Only time will tell. When you consider how much you spend on a pair of waders. A tube of repair gunk at a £10. I think i will get another tube to sit in the draw as backup. Have fun .
