Last year we had to take back a favorite tube to Costco because we couldn't patch the leak. I really tried about everything I could put my hands on before the season but they all failed. I'd read about Tear-Aid Type B on Overton's and found it at a local store and picked it up. We had our new HO tube, same as last year just a year newer out on our week long vacation, sure enough it had a similar 1/4" rip near a seem like the other one did.
I started off putting some Sevylor Air Seal Vinyl Repair on the rip, put 5 coats of it following the directions. I'd used it before and didn't hold but my confidence in the Tear-Aid wasn't there so figured two was better then one. After letting it dry I cut a piece of the Tear-Aid tape and applied it, rubbing hard as directed. Directions say is holds 100% within 24 hours and 50% immediately, we opted to use a hair dryer to speed up the process.
I can say that within the 2 hours we were back out on the water and the patch(es) held for the next two days of use just fine.
