Stormsure is one of my favourite products as so versatile, originally I started using it for repairing wetsuits. This is a very thick glue so it acts like a filler. If you have taken a chunk out of something , you literally fill the hole with it and it requires no patching. I then moved onto dabbing it on holes in fabrics including drysuits. It forms its own skin therefore completely airtight . It does dry fairly thick so not ideal underfoot and even the clear is a milky white so not invisible, but does mean you dont have to worry about colour matching. Main problem I had was the tube going hard after I had opened, despite keeping in fridge or freezer. So when they introduced this 3 tubes of 5G set I was actually happier as I now waste less, and you can carry unopened tube for emergencies.
