So, the Kathmandu PU coated pack liner I've been very happy with for a long time is finally leaking a bit. The tape sealing on a bottom seam is failing in a couple of spots. Of course, they don't make them any more. Can't find them anywhere else. Not sure what capacity - probably 50L. It's tall, not squat, which allows me to slide the tent down beside it after I've packed most things, if I'm packing up in the rain. I've tried dead dog bags and garden bags, but I find they need replacing often, and don't have the benefit of being the right shape for my purposes.
Would silicon on the outside of the seams work??? I'd rather leave all the tape on as extra insurance. Or is there something else I should use?
Ta for your thoughts.
