I'll give it another try. I'll probably still upgrade to a new tube, but maybe I can give my son my old tube without a leak. ThanksI just fixed a slow leak in my Clearwater. It took two arduous try’s with the bladders out. 1 very slow forming clear bubble. Not a stream of bubbles nor did it form quickly. If you’re interested try soapy water (again I’m sure you did already and let it sit for a while and try multiple times. If there’s a leak there’s a hole but sometimes they are very slow to show. Tear-aid type A and I’m happy.
PS just got the Lost Creek. Not sure of the business model but can confirm it’s made by Outcast and has paperwork stating 5 year warranty.
