urethane bladder repair tape

[drowning_flys]

Thanks flygoddes and tubedude reason I ask is I had a pinch hole from when it was deflated and the bladder got between the frame and the bed of a truck for 250 miles (dont let friends use your tubes) and i used the tape but it only held for about 12 hours I removed it and scuffed it up with sand paper cleaned it and reapplied a new patch going to air it up tonight and see if it holds but if it doesnt i need other options. Bucks swears its urethane as its an old southfork 2
