I haven't been on my float tube in 7 years and it's been stored in the garage for that time. After my last trip to Perris, I realized the advantages of having a tube. After I got home, I inflated my tube to see if it was still good. Within minutes, I remembered why it's been 7 years since I've been on my tube... There's a small pinhole in the bladder. My question is: what do you guys use to patch up the bladder? I was about to buy this stuff called Aquaseal at Sport Chalet, but decided I'd ask the experts here first. Is this stuff any good? Thanks in advance.
