i've got an old rucksack that i've used a lot and want to keep it going, but on the inside, what looks like the water proof coating is peeling off, anything i can use to sort this out?
Incidently, what brand & size is your rucksack. I ask because some ruckies are worth continuing with, while others, well, it was the lining that was giving some solidity ( even holding it together) to the bag & so cease to be 'usable' once the lining has gone.
