dont know if this helps anyone , but everyone on here has been so helpful i thought i would try and return the favour with any little things i find !!

I had a leak in a backpack that i had , every thing else was fine but it (POURED) water, so it was pretty much useless tried patching it up with various things , super glue , putty , resins ect .., nothing really worked for more than a day or two

then my mate sugested i use this stuff that we use on hockey sticks called tk magic which is a two tube pump thing ?? (haha)
£ 6.00 and was absolutly brilliant not a leak since

you can buy it from hockey shops or online on the tk website

hope this helps someone !!
