I got this stuff from a Surf shop it is called Quick Fix -Rubberised, the guy in the shop says they used to sell Aqua sure, but this stuff meant to be better and you get a lot more. I sorted the inside leg of mine that got ripped on barb wire and it works great.I tried it out on Saturday no leaks , :D checked for peeling but perfect seal well pleased :D. Cost me ?7 but you will get it cheaper than that if you look around.
It is a2oz or 57g tube. :D :D
It takes 24 hours for the cure Col .
